One of the most useful aspects of YC are the weekly dinners. You know, face to face interaction with other entreprenuers. It's very valuable. It might be worth while to organize a weekly gathering for entreprenurs working on similar projects.
I've thought about the same. One of the things in the extended profile thing that I'm building is location. In some of the hotspots a monthly dinner would definitely be cool.
Hmm, ok, what the hell, there is no try, only do. If you're in Berlin, dinner at my place Saturday the 19th. We'll do it at least monthly. Contact me. Just between our apartment and my next door neighbor we've got three startup junkies, and that's already enough for a good conversation and to put the hurt on a case of beer.
I'll set up a calendar for startup-related events (that need not be related to news.YC). I think it'd be good to have a place where people can post in their blogs and try to get groups together. I think as soon as you've got three people together you can already have a meaningful meetup.
