Ok, if you haven’t noticed already, I have a thing for following real estate apps, particularly those powered by a great map UI… webmap services and real estate go together like PB&J and the two disciplines are simply perfect for each other! Another fine real estate mashup is now available from the people at HGTV – enter Frontdoor.com (great name!) The site is well designed and provides a great mashup of real estate listings which is easy to navigate and has a great foundation created thanks to the use of the Google maps API to power the site’s interactive mapping… once again a nice simple, functional resource that’s easy to navigate and appears to do what you would expect… nice job!
