> Maybe someone with excellent writing skills and having demonstrated reading all the documentation and FAQs is still asking for help in a respectful and intelligent way, and so maybe you engage.
You mean it gets tiring to find the entertaining messages instead of the random trash? Because it doesn't matter how much effort the sender has put, or how intelligent his request/question/contribution/comment is. If I'm not in the mood, I will ignore it. I'm doing it for the fun, not to provide free support, so I will only read stuff that is fun to me. Obviously being an intelligent question is likely to add points, but it's not always the case.
It's not like this is race to see who is the least Torvalds-like of the bunch. It's 100% OK to just ignore everything. The people who complain "I had to moderate comments while my mother was in the hospital!" look like they have an addiction, or a runaway hobby.
I even have an online board for this sort of requests and generally I just read the subject lines. Fortunately for them, once your software is popular enough, a lot of people seem to like to reply to other people's questions, for some reason.
