It was that line about his "Mum finding a freak-show she could sell him to" that gave the impression of a frustrated teenager :-D
I see it was written by a male, and actually, I didn't notice that first time and though it was written by a female!

But anyway, it comes across as a rambling, a 'speaking-out-loud' sort of thing by one who is obsessed with social networking, but who has realised the only thing it's done for him is alienate him against the rest of society.  I think there's a lot of truth in that, so like I said, good writing.
