Trulia launches yet another innovation today called Trulia Snapshot that further shows that they are the leaders in capturing and managing listing information for consumers. (disclosure: I am on their industry advisory panel)
Its one of a number of innovations they have released that deals specifically with the visual representation of data.
Trulia Snapshot is a tool that allows you to browse properties listed for sale on Trulia in a very different way. The photos are placed over a map of the local you are interested in and you can view by most to least expensive, oldest to newest, etc.
My favorite feature is being able to see where the specific listing sits within the housing stock available for sale.
