I was reading an article on ZDNet today which states that Facebook has overtaken MySpace in terms of world-wide unique visitors. It's kind of surprising for me since I had heard Facebook traffic has been declining. Analyss suspect much of this growth is due to an increased presence overseas, which does make sense.
Advertising dollars has still been a big problem for sites like Facebook, but it seems some recent hires in the PR department might be a way to turn their "image" around a bit. I still use Facebook reguarly, but even with the new design of MySpace, my participation there has dropped considerably.
How many of your are on social network sites like Facebook and MySpace? Do you find them useful?
