What IRC channels can I join to meet startuppers?

After writing for Valleywag for over a year, I want to start a company, so I want to talk to other startuppers. I've noticed a good vibe on YC, and I also enjoy using IRC (most often on #joiito on freenode). Is there a good IRC channel where a lot of startuppers go?

As far as I know there aren't any good irc channels for startups. Founders tend to be rather busy so asynchronus comms such as news.yc works better.

I hang out with a bunch of other startup hackers in #polymorphs on niven.freenode.net

People starting up don't have time for IRC. (Or news.YC...Oops.)
