This site lets you look at home values in your area. It already surprised me to see how prices were in my area.
Needs work on the map interface and the firefox support.
And what a wierd name.. wtf is a zillow?
Ah, here we go:
Once they hatched their idea, they needed a name. "Zillow" evolved from the desire to make zillions of data points for homes accessible to everyone. But a home is about more than data - it is where you lay your head to rest at night, like a pillow. Thus, "Zillow" was born. They knew they had a winning name when employees began talking in Z-language and newly-minted words starting with "Z" popped up everywhere (e.g., Zestimate?, Zindex?).
