Over-50s get networking website

http://news.bbc.co.uk/1/hi/england/kent/7070667.stm

I keep wondering why do you need separate networking website for over-50s? I have been using the same browser, same computer as they might be using. Probably, it is more simple to use, but so is Facebook or Myspace or Orkut? This is just another marketing gimmick by the site or company that has launched the site to attract revenues in ads!

Am I the only one thinking in this way?
