I like forums, but for some things they are a bit stale. It's like having a pen pal as opposed to going down the pub with some friends. Some great ideas are born from discussions at the pub over a drink.
I created #startups on irc.freenode.net so feel free to come and chat/hang out there.
The problem I have with IRC is that there is no decent search/logging option (and please don't mention bots). And I hate having to nag everybody with a question that was asked a few days ago or answering a question that was already asked unless there is some new twist.
How about setting up a 37sigs campfile account? The only problem is that I'm not sure that we'll fit in there (the premium account only supports 60 users simultaneously chatting)
