I think within the last month the implications of social over search have really become more apparent to me. With search you’re pulling stuff in, and with social you’re pushing stuff out and sharing it. You’re developing an intellectual and social identity in doing so. You can depend on the wisdom of crowds to do so, to set up your media streams — but in my experience? Crowds: not that wise. I wouldn’t want an informational diet that depends on what’s trending on Twitter.
