Very interesting. I had the same kind of idea with my site and made some pretty neat maps of pricing, crime and school scores, but I can tell you what I found out -- people don't care that much about digging into data like you think they would. Users just want a better home shopping experience, with just a little trustable advice sprinkled on top. It makes sense now, but I was stuck in "cool product land." I wonder if Movity found the same thing in their customer development. I've always wanted to use Craigslist data on my local real estate site but I know it's 100% against their TOS and I didn't want to give them any more headaches than they currently have. It's great to see that people are able to do it but it just makes the whole situation more inscrutable. So I guess it's okay if you don't get caught or have good intentions. Well, I guess that's better than nothing.
