NY Real Estate / Broker Google Mashup

Just launched is this new mashup that allows you to search for apts in NY and view reviews/feedback of the actual properties and brokers.

I feel like most of these Google mashups are really messed up and don't ever amount to much because people don't contribute to them. You can't have a system that works if people aren't engaged and doing their part to make it have depth and resources.

So that might be the challenge here. If this catches on then it could be brilliant and rival all of the bullshit that clogs up Craigslist. If it doesn't....not so much.

I feel like the whole broker world is somewhat inevitable, so that part of it doesn't bother me. However, I wish they would list which brokerage firms...some of them are total dogs.

Thoughts?
