Hacker news IRC channel?
I use IRC quite a lot to quickly find the solution for small problems that Google doesn't solve.
However all channels are fairly specialized and I sometimes feel the need to discuss more general concepts that span several categories. That is normally not appreciated on IRC, you'll be asked to stay on topic.
Hacker news feels like this endless well of knowledge that can be tapped and it would be cool to have a Hacker news channel on IRC. Apparently #startups on freenode is what most people use. For lisp stuff, you can find a lot of people in ##sicp on freenode. I think #startups on irc.freenode.com is more or less the official channel.
