So much that I have read about the 'Social' sites have kept me away from them. I suppose we only get to read the bad things that happen.
Be selective and wise in your decisions for who you are contected too. Most of those people are just all over the place and care very little about who they allow and such. Social networks can be used for a very professional means of contact; if it is used correctly!
I use them a lot - plus I'm married and have 2 kids. But I'm not out there to get into trouble. Just find better things and make friends and contacts for professional reasons. Others are not like this and you will find they are the ones with problems.
Also another very professional site is Linked In or that is http://www.linkedin.com/
Which allows people with about the same interest to find each other to share their ideas and works.
Also the new trillian beta 4.1 has a lot of better ways to keep track of these sites without being in a browser. I use this and trillian 4.0 to keep up with mainly my tweeter followings and the such.
