Description
Summary:We investigate Chinese BBS-Tianya Club collective users’ behaviors empirically and confirm that emerging attention on posts follows q -exponential novelty decay. We analytically derive a general model of reply asymptotic behavior, showing that the microscopic rate of change obeys the Gibrat proportional effect and q -exponential novelty decay. Rigorous statistical comparison and tests confirm that the empirically observed distribution of replies is subject to power-law distribution with an exponential cutoff, which is consistent with our theoretical analysis, suggesting that the proposed model effectively describes the collective replying dynamics on BBS.
