Just
found a nice map of the distribution of social networking websites over the world, such as
orkut,
myspace, or
studivz.
Too bad it doesn't include their business brother pages such as xing or linkedin. But it is interesting anyway. For example I didn't know that orkut is only dominant in brazil and india now, once I had an account there too. And interesting that studivz is listed in Austria and Germany as primary social network page, although it is only intended to be used by (ex)students. (Yep, I have an account there too, add me if you like.)
I'm from Ukraine and I accept -- a lot of us uses LJ (LiveJournal). Also if we take 100% of all us who using some instant messenger -- it will be 90-95% ICQ...... and 5-10% is all other like Skype, MSN, Yahoo, AIM etc. Also IRC networks popular enough.
