While I'm not disagreeing with your conclusions, I came to a completely different one.
All of the questions linked above have more than one thing in common (the first being the subject matter). What is more of a nuisance in my mind is that the questions are all very short. Concise questions are fine, but these are also very repetitive questions, and aren't showing much in the way of motivation. I'm surprised how few responses there are of "do your own work".
I'm not really inclined to reply to these threads, but if I were so inclined I think there would be a lot of RTFM involved.
