If I tell someone my location, I keep it general. I do not post my specific city on community sites like MySpace, nor do I post the school(s) I've attended or, if I worked, where I was working. Makes it quite easy to find you. I've seen on a talk show (no longer airing) how people can use very little information to track you, such as the weather: If you live in, say, CT and mention it's cloudy, it's possible for a person to narrow where you live or places you hang out at simply by looking at the weather report for CT to see which areas are cloudy today. I've seen how the most innocent things you post can be used against you. If someone sees a kid has posted one of those big surveys with questions like, "What's your favorite ice cream?" or "Hamburgers or hot dogs?" and they get a hold of your phone number (for instance), he might be able to convince the kid or a friend that he knows you, who might give him more information to find the kid. There are other scenarios, but you get the idea.

All that said, I still post information (such as on those surveys), because I want to enjoy the Internet, and I don't want to let fear keep me from that. I believe in taking reasonable precautions. I mean, you'd have to avoid a lot of fun stuff if you really wanted to be safe on the Net. And totally avoid it to be 100% safe...or actually, there is a small possibility of people finding you or contacting you even if you don't use computers or Internet, because people finders include addresses of people who aren't computer users. Trust me, I know.
