There are a number of useful statistics surfaced on reporter.a.o about project mailing lists and such, however none of the statistics track activity on PMC private@ lists.
I believe this would be very useful to have a larger sense of how active different project private@ mailing lists are. In particular, the ASF as an organization often uses the pmcs@ alias - going to all private@ lists - as a way to inform PMCs of important ASF activities and policies (like recent branding recommendations and CMS changes). How effective is using pmcs@ to communicate important information to *every* project? Do we have a sense if all projects are really listening in a timely manner or not? (I think a number of projects don't!) I would love to see mailing list statistics over time for private@ lists, including subscribers, new posts, and especially new replies somewhere that either PMC members/committers or Members can access. Replies are important because that shows people are actually discussing issues at all, or not. I.e. in many cases if there's a major change or question being asked of PMCs, you'd expect that the pmc would have a brief "hey, how should we respond/does this affect us" thread on their private@, and then go back to the original questioner. If there are a lot of private@ lists where there is typically no replies over time, I'd be a bit concerned that the PMC may not be taking action (or at least explicitly ACK'ing) important items in a timely manner. Comments? I'm figuring this is an INFRA ticket, which an infra team member notes is probably not a lot of work. - Shane
