This pretty much nails the sentiment I took from the story. He isn't so much complaining or railing against Facebook, but kicking himself for being, in hindsight, so naive. Not that anyone could blame him for it though. I mean, it certainly made perfect sense at the time, in fact for most of us, it still appears to make a lot of sense which is precisely why he is putting out these words of caution. The one line summary seems to be: Facebook and Twitter represent a closed model of social networking, which rails against the very nature of web and internet as a technology platform and it probably won't last. Not saying if I agree or disagree with that statement and prediction, but I definitely see the argument.
