If you ask an Irish kid what Facebook or Myspace is, he'll look up at you blankly. All teenagers and young adults in Ireland use Bebo so naturally I got an account to communicate with my friends. A while ago, I got a Myspace and a Facebook just to be able to compare them to Bebo and they were okay. Prefer Bebo, really. I have a Livejournal that is strictly online friends only to make up for the offline friends only Bebo account. There's private data on the Bebo account but I don't really care about that. I think we all know deep down that we're decent human beings here. No, the reason my Bebo is kept secret from the online world is because of two reasons. The first is that my friends in real life will be wondering where all of these international people came from. The second is that I don't know anyone online who has a Bebo anyway, so yeah.
I'm also a member of various VBulletin communities. And before you say that they aren't social networking sites, I want to know what you think VBulletin was turned into when the 3.7. upgrade came into play.
