I think I am addicted to Social Networking. It has become quite clear to me as I signed up to LinkedIn. I am not sure what it is about these sites. Each one provides something different. Some are really way though, but others are pretty good to the point that they are very addictive. So I will just give a list of all the sites I am on. (Editor's Note...Don't Judge Me!)
I have kept an account on these sites because you never know who you might run into. I do not normally erase a profile. I do have some on sites I rather not say due to personal reasons! I think social networking can be fun, until they get boring.
I know there are other sites because I still get invites. Maybe I will check them out. But, one thing is for sure, I do not pay to Social Network.
