I notice that lately this mailing list seems to be almost overrun with a lot of noise: complaints about blocking, diatribes about perceived wrongs, requests of various kinds. Whereas what I would really like is a place where the most committed and experienced Wikipedians can discuss more serious issues in a bit of depth: where the project is going, recurring problems at a more abstract level, general issues more distilled than "omg [[foo.com]] is so crap!" etc.
I think a fair bit of the complaining is by experienced editors. You'd lose most of the more trivial "I've been blocked" emails, but that's all, and those emails aren't hard to ignore.
