I remember seeing people when social networking go started, it was a free for all wild west type of mentality.

What people do not realize is this data once populated on someone else's sites is NO longer yours.

All social networking media sites are harvested and/or the data will eventually be used as it is being used today. Future employers search these sites looking for YOU and what you have put out for the world to see.

I have not and will not use these sites, as the information is not deletable, as with Google I do not use their services they offer. There are many scrappers out there that let you scrap their search logs and never use them.
