I’m not an active member of any social networking services — I think I had MySpace and Facebook accounts at one point, but never made use of them and got tired of the e-mails.
Here’s an interesting look at the market share (so to speak) of different networking sites on a continental basis. A lot of folks not talking to each other, so to speak.
MySpace dominates the U.S. and Australia, while Facebook holds the lead in Great Britain and Canada. And contrary to what you might think, Google’s Orkut isn’t as also-ran as some like to paint it — the site is popular in both Brazil and India.
Also worth noting is that, while interest in sites like LiveJournal and Friendster have waned in the U.S., both have found strong followings overseas — Russia and South Asia respectively.
I’ll just settle for my blog, e-mail, and chat, thanks.
