Amazon has just bought Twitch, a video-game livestreaming site, for close to $1billion. It's reportedly the world's largest gaming community.
Remember GoodReads? The social reading website, with an emphasis on books, catalogues, and reviews, startup up in 2006 as a site for members to discuss the books that they loved. Amazon purchased GoodReads in March 2013; not long afterward, it was enmeshed in accusations of censorship and stifling creativity after it reportedly deleted hundreds of user reviews and ratings without warning, sparking a backlash by a small but active group of members.
Buying a social network doesn't just mean you've purchased another outlet for marketing your products—and that's exactly how many Goodreads members felt post-acquisition. It means you have a community to tend to. Manage that badly, and you get disillusionment. Disillusionment leads to frustration, frustration leads to anger, and anger leads to the Dark Side. Or at least to out-migration, often of the most innovative or talented members.
