If you don't have friends that can be your cofounders, these events really are the next best thing. You can immediately see who is interesting, who works hard, and who just talks a lot.

Interesting article. I've heard of future partners meeting during Startup weekends, and this seems like another great place for new ideas and like-minded individuals.

It makes a ton of sense to find co-founders at Hackathons.

Lots of startup teams find each other at previous jobs or when working on a school project.

Gotta say that you really get to know whether you want to work with someone after going through a hackathon with them. Would be a great standard interview process!
