Nice idea. A lot of people are doing this now but no one does it well. Nice weekend hack.

Didn't see a compelling value proposition why would users utilize this vs. Google Maps / Yelp or other vertical maps instead

cool idea, needs to be developed more. not clear how this evolves from 'feature' to product/business.

I struggled to see this being used on a regular basis by users.

look at http://www.cra.sh they're doing some of what you're working on.

very nice app, a good mashup of APIs, but would like to see more unique value added. nothing here that i can't do by using multiple services.

Think it's a crowded space....

Monetization will be key.
