I seldom use Facebook, but when I do ….
Actually, I have so little experience with Facebook that I am ill prepared to offer anyone advice. However, I do appreciate the popularity of the site and the interest adolescents might have in creating an account.
I though this NY Times tech blog post offered a nice summary for new users. Good advice on setting up an account, learning the ropes and staying out of trouble.
P.S. – take the time to read the comments.
