We are now #fedwiki on irc. I haven't registered us as an organization with freenode, do we want to do that? http://freenode.net/group_registration.shtml
For those of us without a normal irc setup i'm testing out running a web irc client for us on my server at subway.nrn.io, feel free to use it, but don't rely on it, i'm still playing around with it. It's using https://github.com/thedjpetersen/subway.
You could go a step further and use your server also as the IRC server. Who needs freenode anyways? : ) This is all about independence and decentralization, right?
That would be tempting, there is a node irc server, however I've only got the one server and I use it for lots of development stuff, so it's down a lot.
IRC is now mentioned in the "how to participate" section of the primary ReadMe.
