this is an interesting idea ->what are you looking to do?
I'm not sure yet in which direction I should move it, but I wanted an app which allows to quickly post and find geo-located ads and messages divided by topics.
I really like this idea/interface, this could be a great layer to apply on or replace Craigslist's places to rent section, it reminds me of a craigslist-ified version of the mls.ca website.
