Have you tried getting a shared office space somewhere? Maybe even where other programmers sit as well? I share an office and see people that way. If you share office with people in the same business you can also easily discuss any problems that occur and maybe get help?
that's my plan, once I get enough paying work in it to pay the rental. A private desk at Portland's Nedspace is $450.00, a "hot desk" is $350.00. I don't really need my own personal desk but the private desk option gives one 24-hour access, which I really do require as I am a confirmed night owl.
Until then, I hang out at wifi spots but it is uncommon to find other coders at any of them.
