From my experience, you get much better generalized startup feedback, but it's frankly harder to get true user feedback unless you're building something for SF types. I tend to filter a lot of my more general consumer product ideas through friends who DON'T live in SF because I want them to not be comparing it to every other startup they've heard about recently.
