Channel9 IRC channel
Rob Chartier points out there is a new irc channel dedicated to channel9, and even Scoble has stopped by so far. I used to use IRC a lot more when I was coding from home, but now have officially converted to a lurker. When I was just a wee coder, I found it to be an indispensable resource, despite it's sometimes seedy perception. In fact, Rob assisted me quite a bit. Thanks! :)
Rob also points to this thread on channel9, where he plugs a few other irc channels (#mscorlib, #ms.net, #asp.net, #asp) that I also idle in. Check 'em out if you get the chance.
