+1. However it's not easy for all of us to make "co-founder potential" relationships organically. In fact, most of my friends are not tech savvy or entrepreneur minded.
I have the exact same problem. While my friends all have fantastic minds, none are particularly interested in the "risk" of starting a business when they are just getting on their feet. I try to involve myself in local societies and organizations which have the sort of individuals I want to work with.
Alternatively, there are other online forums which add a nice structure to the process of finding a co-founder. Tristan Kromer has put together http://startupsquare.com which he has made promising progress in. I've also put in an application with the (fairly new) http://cofoundersnetwork.com. There's an entire section of questions based around this here: http://www.quora.com/Finding-Co-Founders/
And while the option isn't available for everyone, sometimes going to the mountain instead of waiting for the mountain to come to you feels more productive. I intend to move to Boulder, CO where these crowds are much more abundant than where I am and do some schmoozing there to grow my network. And if schmoozing is hard, I hear Toastmasters is a fantastic experience everyone should try.
