You've probably never heard of Orkut (unless you're Brazilian) and I didn't even recall having an account with them, but yesterday I received an email from Google telling me they were closing the service down. Orkut was Google's version of Facebook; launched in 2004 it became one of India and Brazil's most popular websites. However, Facebook e clipsed it in the rest of the Western World and if you live in the West (outside of Brazil) then you've probably never heard of it. Google say that the growth in YouTube and Google+ means that Orkut is no longer needed. It lasted longer than Google Buzz though, which barely lasted a year.
