27 million users
There might be 27million registered users but that doesn't mean that 27million actually use it.
The article was a long time ago and I'm guessing it was a PR released to try and stimulate some kind of investment rather than actually trying to sell it. Social Media changes pretty quickly and Nasze Klasa missed out when they had their chance. Facebook is trying desperately to keep it's users while Twitter & Tumblr are gaining more & more everyday. Does anyone remember Friendster, Bebo or Myspace, they were all bought for big money but it was too late, only a proper gobsh*t would even contemplate buying it.
It seems that facebook is everywhere at the moment but from what I've seen it's pretty much plateaued and unless it gets into Russia & China it's popularity will start falling away in the next couple of years, even as it is there's been plenty of press regarding "Leave Facebook" days over their dodgy security features.
