Question: who actually uses those "share this" buttons cluttering up all websites? Seriously, who? Sites are increasingly looking more like this graphic that accompanies the NYT story about those social media buttons. While I'd like to say these are complete bullshit (and I try to convince clients that they are), you can't ignore that ~200 retweet count on Techcrunch posts. Do any of those really matter? Are those influencers, or bullshiters?
(Similarly, isn't it crazy that no one has stopped and wondered how the hell ShareThis and Bit.ly, like Pluck before them, became hot startups? It's like once the legitimacy of user-generated web 2.0 companies was accepted, no one dared ever question the importance of the intermediary ever again.)
