The only upside to Facebook is the fact that you preapprove everyone that can see your data. Twitter however, doesn’t have this privacy feature and Mark Cuban has just figured that out. Valleywag just recently annouced that he has been fined $25,000 for slagging referees by the NBA.

This once again gives us a reminder that everyone can see everything you post on Twitter. If you plan on posting things that are private, you might want to set up Facebook with your close friends. Just make sure to restrict wall updates to people that you know won’t fine you for talking smack about people. Or just keep it to email.
