Zillow - Big Brother?

Is there any privacy any more? We've been talking about "Big Brother" for a long time and especially since everybody's on the Internet.

I've googled myself several times and found a lot about my author doings, but not about my personal life.

Then today at work, my friend told me about "Zillow". It's a site that shows aerial pictures of your house and it estimates its value.

I don't think I like this. It was bad enough that Google's taking pictures of everything. But to estimate the price?

How the heck is Zillow estimating my home's worth as one price and the attached home at a higher price? No one's come to check the inside of my house.

Here's the address if you want to check out your house.
