Could stackoverflow.com work for other fields?
sgrove: I think so.In fact, I believe it so much, that's my startup: http://www.chuwe.com - "Stackoverflow for startups and small businesses."As brandnewlow pointed out, starting it is a massive uphill battle - chicken and egg problem as it were. The software's only small part. We're attacking it in what we hope is a novel way, but you would have to find an approach unique to the area you were targeting, I imagine.If you're interested, I've been planning on open-sourcing chuwe in a bit after we make it a bit more robust. Contact me and we can work out something if you'd like to just take the software and modify it to your own niche!
