Rather surprising infographic showing amongst other things what services are winning and losing users.

I feel some pity for Ning, considering what an advanced and useful service that is for setting up your own forums, yet nowadays I guess people set up Facebook pages etc instead.
I was also surprised such seemingly worthless services as Habbo and Imvu are very popular among younguns. Imvu had 100000+ users logged in when I last checked. I figure I’m too old to appreciate virtually furnishing my home etc.
