Just found a neat site the other day: Zillow that uses a lot of "Web 2.0" tech to give you your house's value. It's pretty accurate (maybe off by about 5 months). Also gives you all kinds of details like how many acres, bathrooms etc... It's somewhat scary how much detail you can get about a persons life now on the internet. Given just a name and city, I can usually find a picture of your house, how much you paid for it, and when you added that new bathroom thanks to the internet. For example, here is Super Bowl winning coach Bill Cowhers house.

I'm not sure quite that much information needs to be made public, and is why when we created SearTech, we thought very carefully about our privacy policy. We never collect any data without telling the customer exactly what we are doing, and we would never release our contact information to a third party. I would rather risk a few pirated copies of our software then collect information without the person's knowledge.
