Social media content typically has a short window of relevance and engagement. An advantageous objective metric is half-life. It’s the time it takes for a post to receive half of its total engagement (such as likes, shares, and comments). Understanding post half-life helps inform strategic and tactical decisions, including the frequency and timing of content publication.
First published in 2018, Scott M. Graffius updates his "Lifespan (Half-Life) of Social Media Posts" research annually to account for evolving algorithms and other changes on platforms over time. It draws on large-scale, multi-source data and has been featured by businesses, government agencies, academic journals, professional associations, universities, and researchers globally.
The 2025 paper titled "Platform-Specific Data Decay Patterns: A Comparative Study of Twitter, Reddit, and TikTok" (Kaleel et al.) was published in MEDAAD (Vol. 2025, pp. 8-26), a journal associated with Peninsula Publishing. The authors focus on a comparative analysis of content decay (persistence over time) across Twitter (now X), Reddit, and TikTok. They present a persistence-aware metric called the Decay Score (DS) and discuss challenges in social media research due to platform-driven data loss. The topic is noteworthy because data decay has implications for research reproducibility, methodological validity, and the interpretation of longitudinal studies involving digital platforms.
That Kaleel et al. paper cites Graffius' research. While a careful reading makes clear that Graffius' work is distinct from the study's framing, methods, and conclusions, citations can sometimes create perceived alignment where none exists — especially for readers who may not examine the full context in detail. For that reason, Graffius provides the following objective, evidence-based assessment.
Select excerpts from the paper are shown below.
1. Strengths
The primary strength of the Kaleel et al. paper is its focus on the transient nature of online content as a result of API changes, moderation decisions, and user or platform actions. Its attempt at cross-platform comparison contributes to broader awareness of platform-specific differences. Additionally, the discussion reinforces the value of archival resources and persistence-aware methodologies in addressing challenges associated with the availability and longevity of digital data.
The preceding content (1. Strengths) highlighted the merits of the paper. Points 2, 3, 4, and 5 cover weaknesses, limitations, and other concerns.
2. Claims of Novelty
The Kaleel et al. paper overstates the novelty of its contributions. The proposed Decay Score is a percentage-loss metric conceptually similar to established attrition, survival, persistence, and availability measures used in prior research. Comparable approaches already appear in link-rot, digital preservation, and content-availability studies under different terminology, yet the paper does not meaningfully engage those prior works.
3. Methodology
Methodology is the Kaleel et al. paper’s most significant weakness. Sampling details are vague (random and purposive/thematic on political/viral content) with no sample size, power analysis, or clear protocols. Data collection relies on Tweepy, PRAW, and Selenium without addressing rate limits, terms-of-service compliance, or related controls. Decay classification is subjective. Additionally, there is no evidence of validation processes. These shortcomings make the study effectively non-replicable.
4. Results, Data Presentation, and Implications
Results in the Kaleel et al. paper are largely anecdotal and descriptive rather than empirical.
Referenced charts and tables contain vague or placeholder data, and retention claims lack supporting statistics, error bars, or transparency. No open dataset or supplementary materials are provided, making it impossible to verify significance or rule out sampling bias.
The discussion section of the paper highlights issues such as epistemic risks, archiving needs, and impacts on political science and misinformation studies. However, it overgeneralizes without appropriate evidence. There is also confirmation bias in framing ephemerality negatively without acknowledging its potential benefits.
5. Citation of Graffius' Work
The Kaleel et al. paper includes Graffius’ "Lifespan (Half-Life) of Social Media Posts: Update for 2025" in its references and cites figures indicating that the engagement half-life was 49 minutes for Twitter/X and 155 minutes for Reddit. Those values are correct.
However, there is a significant conceptual mismatch in how the cited research is positioned. Graffius’ research measures engagement half-life, a relatively (typically) short-term metric of audience interaction. By contrast, Kaleel et al. examine long-term content decay through deletions, suspensions, and unavailability over months. These are distinct constructs with different definitions, methodologies, and scopes.
Because the two studies address different constructs, Graffius’ work should not be interpreted as validating the paper’s Decay Score (DS) metric, moderation conclusions, or specific longitudinal claims. The issue is the paper’s application of a separate engagement-based metric within a different decay/persistence framework without adequately distinguishing the underlying concepts. Accurate citation requires that sources be represented within their original definitions, methods, and scope.
By applying Graffius’ engagement metrics in a decay/persistence context without clearly differentiating the underlying constructs, the paper may create an impression of methodological alignment or endorsement where none exists. Graffius does not endorse the paper.
Kaleel et al. focus on a relevant challenge in digital research: the persistence, availability, and reproducibility of social media data in environments shaped by platform changes, moderation, and user behavior. However, the paper’s proposed solutions are undermined by methodological opacity, insufficient empirical validation, unsupported quantitative claims, limited engagement with relevant prior research, and other issues. Its citation of Graffius’ engagement half-life research should not be interpreted as support for the paper’s Decay Score, persistence framework, or conclusions, as the two studies examine fundamentally different constructs. Robust research on social media data decay requires clear definitions, transparent methods, reproducible evidence, and careful distinction between distinct separate measures. Accordingly, readers should treat the paper's findings with caution.

Social media content typically has a short window of relevance and engagement. An advantageous objective metric is half-life. It’s the time it takes for a post to receive half of its total engagement (such as likes, shares, and comments). Understanding post half-life helps inform strategic and tactical decisions, including the frequency and timing of content publication.

It draws on large-scale, multi-source data and has been featured by businesses, government agencies, academic journals, professional associations, universities, and researchers globally.
The 2025 paper titled "Platform-Specific Data Decay Patterns: A Comparative Study of Twitter, Reddit, and TikTok" (Kaleel et al.) was published in MEDAAD (Vol. 2025, pp. 8-26), a journal associated with Peninsula Publishing. The authors focus on a comparative analysis of content decay (persistence over time) across Twitter (now X), Reddit, and TikTok.

Select excerpts from the paper are shown below.
Critical Analysis of the Kaleel et al. Paper
1. Strengths
The primary strength of the Kaleel et al. paper is its focus on the transient nature of online content as a result of API changes, moderation decisions, and user or platform actions. Its attempt at cross-platform comparison contributes to broader awareness of platform-specific differences. Additionally, the discussion reinforces the value of archival resources and persistence-aware methodologies in addressing challenges associated with the availability and longevity of digital data.
The preceding content (1. Strengths) highlighted the merits of the paper. Points 2, 3, 4, and 5 cover weaknesses, limitations, and other concerns.
2. Claims of Novelty
The Kaleel et al. paper overstates the novelty of its contributions. The proposed Decay Score is a percentage-loss metric conceptually similar to established attrition, survival, persistence, and availability measures used in prior research. Comparable approaches already appear in link-rot, digital preservation, and content-availability studies under different terminology, yet the paper does not meaningfully engage those prior works.
3. Methodology
Methodology is the Kaleel et al. paper’s most significant weakness. Sampling details are vague (random and purposive/thematic on political/viral content) with no sample size, power analysis, or clear protocols. Data collection relies on Tweepy, PRAW, and Selenium without addressing rate limits, terms-of-service compliance, or related controls. Decay classification is subjective. Additionally, there is no evidence of validation processes. These shortcomings make the study effectively non-replicable.
4. Results, Data Presentation, and Implications
Results in the Kaleel et al. paper are largely anecdotal and descriptive rather than empirical.
Referenced charts and tables contain vague or placeholder data, and retention claims lack supporting statistics, error bars, or transparency. No open dataset or supplementary materials are provided, making it impossible to verify significance or rule out sampling bias.
The discussion section of the paper highlights issues such as epistemic risks, archiving needs, and impacts on political science and misinformation studies. However, it overgeneralizes without appropriate evidence. There is also confirmation bias in framing ephemerality negatively without acknowledging its potential benefits.
5. Citation of Graffius' Work
The Kaleel et al. paper includes Graffius’ "Lifespan (Half-Life) of Social Media Posts: Update for 2025" in its references and cites figures indicating that the engagement half-life was 49 minutes for Twitter/X and 155 minutes for Reddit. Those values are correct.
However, there is a significant conceptual mismatch in how the cited research is positioned. Graffius’ research measures engagement half-life, a relatively (typically) short-term metric of audience interaction. By contrast, Kaleel et al. examine long-term content decay through deletions, suspensions, and unavailability over months. These are distinct constructs with different definitions, methodologies, and scopes.
Because the two studies address different constructs, Graffius’ work should not be interpreted as validating the paper’s Decay Score (DS) metric, moderation conclusions, or specific longitudinal claims. The issue is the paper’s application of a separate engagement-based metric within a different decay/persistence framework without adequately distinguishing the underlying concepts. Accurate citation requires that sources be represented within their original definitions, methods, and scope.
By applying Graffius’ engagement metrics in a decay/persistence context without clearly differentiating the underlying constructs, the paper may create an impression of methodological alignment or endorsement where none exists. Graffius does not endorse the paper.
Conclusion
Kaleel et al. focus on a relevant challenge in digital research: the persistence, availability, and reproducibility of social media data in environments shaped by platform changes, moderation, and user behavior. However, the paper’s proposed solutions are undermined by methodological opacity, insufficient empirical validation, unsupported quantitative claims, limited engagement with relevant prior research, and other issues. Its citation of Graffius’ engagement half-life research should not be interpreted as support for the paper’s Decay Score, persistence framework, or conclusions, as the two studies examine fundamentally different constructs. Robust research on social media data decay requires clear definitions, transparent methods, reproducible evidence, and careful distinction between distinct separate measures. Accordingly, readers should treat the paper's findings with caution.

Acclaimed Authority on Teamwork Tradecraft
Graffius is a renowned authority on teamwork tradecraft. Informed by the research of Bruce W. Tuckman and Mary Ann C. Jensen, over 150 subsequent studies, and Graffius' first-hand professional experience with, and analysis of, team leadership and performance, Graffius created his "Phases of Team Development" intellectual property as a unique perspective and visual conveying the five phases of team development.

It provides actionable insights for leaders across industries to develop high-performance teams. Its adoption by esteemed organizations such as Yale University, IEEE, Cisco, Microsoft, Ford, Oracle, Broadcom, the U.S. National Park Service, and the Journal of Neurosurgery, among others, highlights its utility and value, solidifying its status as an indispensable resource for elevating team performance and driving organizational excellence.
