I have about 914 friends, and climbing on facebook, and yes it does increase your anxiety rate. The main reason I have so many is to play Mafia Wars. Many think it is a ridiculous game, but that is what draws me. It keeps changing when you least want it to. However, you also would like to get to know these friends more than just for Mafia, so sometimes you are satisfying the firend urge without having played your game, which is what you wanted to do.
