I think a lot of people, when they have a few moments to spare, but don't want to do anything serious, get on here (like I often do -- :-) and wing it.
But a lot of questions are asked by, evidently, real idiots. There is a saying that there is no such thing as a dumb question. Wrong! You will see hundreds, thousands, of them here. If you don't grant that a lot of the questions are dumb, then obviously the people asking them are.
One big category is all the bimbos who just got pregnant, who have no job, a loser husband or boyfriend, who may or may not have any idea who the fathers are, and are looking for some magical advice. Yet they are too stupid (religious) to take the best course of action. Get an abortion.
Then there are all the doofus' who want to know how much X% of Y is, or other simple arithmetic questions.
A classic, to me, from the other day was the one where someone was wondering if a washer and dryer use more electricity when run at the same time vs. at different times.
I could go on, but I doubt you want me to...
