My project team and I are currently researching the Google Map API vs. the Yahoo Map API for our summer mobile adventure. I have been looking at sites using the map APIs in various ways. To date, the most entertaining is HousingMaps.

Now how can a mash up Craiglist with the Google Map API be so fun and in some cases laugh out loud funny? Go to NYC or SF and start running searches on high end real estate. The map kindly delivers photos and clickable links for the real estate in question and then you get to laugh at the incredibly ugly housing that is be foisted off onto the overachievers of America at outrageous prices with really awful copywriting as cooked up by Coldwell Platinum or some other real estate agent.
