Google launched its first social networking site Google Buzz in February 2010 to try to compete with Facebook and other social media sites. Buzz never really caught on and had its share of problems so now Google is calling it quits. Google Buzz will be shut down in coming weeks so Google can turn its attention to its other social network, Google+.
Google Buzz had its share by privacy and security issues and never had the features that Facebook had. Buzz users won't be able to create new posts after Buzz is offline but they will be able to view their existing content on their Google Profile, and download it using Google Takeout.
Google also plans to tweak iGoogle to make way for Google+. Google will remove the iGoogle social features that it added to iGoogle several years ago.
