Ask HN: finding a cofounder or two

Mashable has an article listing several social networks for entrepreneurs. You may want to check some Quantcast stats to see which sites have the highest traffic from your geographic area.

I'd also take a look at tech / entrepreneurship / startup -related groups on http://meetup.com

I haven't used any of these following sites, but they may be of use to you:

http://cofoundr.com/

http://www.partnerup.com/

http://collabfinder.com/ (more designer focused)

I have heard of people having luck with this:

That being said, it seems valley-centric and I personally have not had any luck with it in the past.
