I heard today in the radio about this amazing new website: www.zillow.com
You enter your address and it gives you the estimated price of your home. It's pretty impressive, with satellite pictures and all!
They registered the term Zestimate. The zestimation of my home was right in the money. The guy who created this thing is the same guy who created expedia.com; he claims that more than 3 terabytes of data was gathered to make it.
Now you can find out how much that old KH is worth too!!!
