As cringe-worthy as it was, I like the comparison between your online identity being more like a diamond rather than a mirror. Obviously I don't want my real friends knowing that I go under multiple variations of 'Kitty' and discuss K-Pop and I don't want people on the internet knowing I'm actually a socially awkward pimply kid. So that's where Facebook always makes me nervous. Like he said, it throws a blanket statement over your identity and you're forced to show everybody a single picture unless you want to go through the hassle of making multiple accounts yourself. But then Google+ doesn't even allow that, forcing you to use your real name. And it's obviously becoming an issue with employers pretty much always checking Facebook now to scout out employees and disqualifying potential employees for one small slip-up.
I don't like how he namedrops his own canv.as site, a shallow meme generator tool, in a keynote about social networking. I was initially interested in it, seeing as it could have possibly been a social networking tool that solves the problem of layered personalities, but not really now.
This post feels like a whole lot of nothing to me. Whoops.
