Honestly, networking. You'll need to vet a lot of people, which means you'll have to talk to at least 10x as many before you find a good match that your comfortable with.
I've also used services like CoFounders Lab, and several others which have been suggested. They're all pretty mediocre at best.
Thanks for the reply. I have been doing that, but networking with people such as programmers is challenging, they don't seem to get out much. I even tried going to meetups and coordinated events, they are just an elusive bunch.
Again, thanks for the reply, i'll keep try to meet people.
Go to meetup.com - Type in the name of your city and search for groups involved in "programming". I live in a technology backwater, and I'm attending two tech events this week.
Works well for me too. And networking is the main reason I work 2 days a week at a co-worker space. I might even visit a another one once in a while to get a feeling for that place (and people !).
