For perspective, we are at #2 above, spreading some love at IIW (the Internet Identity Workshop) toward Indieweb, at a breakout session hosted by Tom Brown. I’ve always liked Indieweb, and have wanted to be involved with it, but have found myself inconvenienced by geography. Not this time.
I also think everybody who wants to be involved in any way with Customer Commons should dig Indieweb as well, since it’s all about giving everybody independent yet engaging ways to work on the Web.
There’s a chat (read only so far for me, but you know now where it is), and an IRC channel.
Indieweb.org is itself a wiki, which can tell you everything you need to know to get started.
