Not surprised are you? No, thought not. Orkut (Google's attempt at a social network) has never set the world alight, Wave was less than a ripple, and Buzz has the impact of a rather elderly bee with one wing. Try as it might, Google simply doesn't understand social media. They rushed out Buzz without consideration, backtracked over the privacy issues and generally 'didn't get it'. It reminds me of the situation 20 years ago when Microsoft didn't get the Internet. They've been struggling to keep up and are finally getting into the game. I wonder at the extent to which social media is going to be Google's really weak spot. Meanwhile it's back to Twitter and Facebook for me, and everyone else I reckon.
