Lifehacker has put together a useful, but somewhat perturbing, guide on how to track people down online.

Among the sites mentioned are Pipl which digs up information about a person Google often misses, Wink which searches social networking sites and ZoomInfo which aggregates professional information.

Try it for yourself. You may be surprised by how much of your personal information is floating around on the Internet. What these tools do is bring together much of that disparate information.

While we might only reveal a little about ourselves on individual sites, a much more revealing profile emerges once all these small chunks of data are brought together. There truly is no place to hide in cyberspace.
