I've been on Facebook for 12 days now...going on 13. In that time I have connected with 360+ friends that I know or who know me. Some are close and some are distant friends, but it's an amazing thing.
I've been on MySpace for 3-4 years...and in all that time I have amassed 38 friends. I think I'll keep this account...but not do much with it.
Facebook...in my adult opinion is much easier and more beneficial for the person looking to stay in touch with their sphere of influence.
