Very nice idea… As for this start up, I’m not sure what will be their revenue stream since this space is:

1. Crowded like crazy. The big guys are there (google, yahoo local, yelp etc’) and some cool start ups like Techcrunch 50 winner – RedBeacon. They are doing the same.

2. Local is very hard because it is a pure tail game. Even if they will try to focus on the 5 biggest cities in the USA first, it is still very hard to build an index and have a community to put comments/reviews/thumbs/scores on all these little business.

We will see…
