The sexual predator problems on MySpace have defenitely not helped the site at all. Not to mention the spam that most members of MySpace receive. As far as keeping up with several social networking sites, I would have told you that being on one, particularly one that has the most participation is sufficient. But then it occurred to me that because the popularity of social networks keeps changing from one year to the next, you could decide on one social network because it's so popular only to find later on that no one goes on it anymore...So yeah, I can see why you're hesitant on joining any social network at all...
