I don’t. Call me old, but I think ‘social media’ like Facebook, Myspace etc. are a fad that will end up hurting a lot of the people involved. Future employment checking out what you’ve written, companies building profiles of you for targeted advertising spam, etc. I can always rely on FreeRepublic however.
Think of how many teenagers are going to be haunted by what they have posted on social media when they are adults looking for jobs.
