Timmy is "dedicated" to his blogging because Timmy is not neurotypical. It is a symptom of his neurological disorder, and destructive of his ability to do things that "normal" people take for granted. Positive feedback for the behavior feeds it. It makes him feel like for his thing he is the master of his domain, that he is special, and that causes him to withdraw from the more difficult, more scary, more real parts of life further into the police scanner.
Because he is both underage and affected by autism, we have a special obligation to look out for his interests. I know, I know, he says he wants to do this. People with mental issues will say all sorts of really interesting things -- for every Timmy there is someone who believes that they bring order to the universe by sweeping the same floor, over and over and over. If Walmart gave that guy an unpaid job, but generously donated him busfare so that he could continue sweeping the floors for them, every one of you would go freaking ballistic. And you'd be right to do it, because it is exploitative.
That the educational establishment is in favor of anything that keeps him out from underfoot is disgusting to me, but not surprising. I say that as someone with experience on both sides of the desk in special ed.
