Where did you find the people who are working on these posted projects, and how did you get them to post?
I think generally, etsy works because they can sell small runs of handmade things at a premium to cover costs (not the only reason). I'm not sure what the costs are to get small runs of circuit boards made, but it may push up prices of small runs of electronics to be much higher than what we're use to paying--and people generally don't think of electronics as being 'handmade' to justify paying the high premium. It's not a show stopper, but it's something I'd watch out for.
That said, it might work for addons for already made platforms like raspberry pi, arduino, etc. I think it's worth a shot to try it out. Keep us posted of your progress.
Initially, I just threw a post on /r/arduino asking people if they thought it was a good idea, then had a signup form for people to start seeding projects before the site was built.
