Sometimes on my own questions and other people's questions, I see users posting very useless comments that just show they only read the title of the question, and blazed through the specifics explained below. I have even seen answers that are like this, and it is extremely annoying, because they basically restate the OP's assumptions as their answer, then the OP has to refer them to the full text of the question and ask the question again. I understand that part of the rules are to read the question fully and understand it before you can answer, but how can we encourage users to actually do this?
