I can't upvote this enough.
I've been really struggling to find something for me in the DC area. I spent a few years at a contractor job... after trying, and failing to launch my own startup, I'm back with another contractor, and it just isn't for me.
I've been struggling with the desire to stay with family and my SO in the area, and the apparent need to move to CA if I really want to be part of the startup community. It's a really tough decision I've been trying to avoid making. I've tried looking on "conventional" job boards like Monster and on more niche ones like 37signals, and only got a few hits, none of which worked out.
Anything that gets me in touch with more startups, especially ones that are hiring, is gold.
