Google Buzz dropped in February 2010 as Google’s big push into social networking, baked right into Gmail so you didn’t even need a separate account. It auto-followed your email contacts, let you share links, photos, and status updates, and tried to be a mashup of Twitter and Facebook before Google+ existed. The problem? People hated the privacy setup—Buzz would publicly show who you emailed the most—and it tanked fast. Google rolled out updates through 2010 to fix privacy and tweak feeds, but by late 2011, they pulled the plug and folded everything into Google+. Buzz is one of those “blink and you missed it” products that shows how even giants can fumble hard in the social game.
