Promote IRC channel for community discussion (chat.freenode.net/keybase seems populated?)

This bug is not about IRC nick proof of ownership, as that would be fairly impossible.

Looks like there are a few people sitting in [freenet channel keybase](irc://chat.freenode.net/keybase), but I've no clue if this is an unrelated channel or if the devs have any interest in being available via IRC.
1. Are the devs interested in realtime community discussion (IRC or the like)?
2. If devs aren't interested, is freenet still a valuable thing for the community to gather with?

Start with the issue's IRC links and its 15-comment discussion; no file, test, or entry point is identified. Done requires a clear decision about whether the project supports realtime IRC discussion and, if so, which channel should be promoted.
