There's been a bunch of discussions all over the places. My vote is outsourcing as much as possible as the community is spread pretty thin on initiatives.
The ones i remember via gitter
Mailing list and community are also good options, easy and simple, but just like oleg's jetty one, it would require moderation (i'm better at moderating than i am at code reviewing, so i'd trade for hosting requests)
Sadly neither of us really pushed it very far. It goes along pretty nicely with my desire to list commercial support offerings, I just havn't pushed that either yet.
