I think we thought your comment was a criticism rather than a straightforward question.
I agree with you and with Quizmonkey that an awful lot of questions on here are totally unnecessary. I am continually surprised that people with sufficient googling skills to have found their way into the Answer Bank seem to be incapable of googling the simplest answers....
But, Robert, you are probably young and fit and get out a lot. A significant proportion of people on this site are really quite old, housebound, live alone or have family/caring responsibilies that stops them getting out and about much...... and I think asking and answering questions on this site fulfills a useful social function, and as you can see by the banter on the KM & MM Links sites (go back to any Friday night / Saturday morning), many of the regulars on this site have formed happy cyber friendships.
Who knows why people really ask questions? I don't ask many, but I answer them because I like the challenge, I like being helpful, I think that more people will pay for charity quizzes if they think they've got a good chance of getting most of the answers they need....and I too have made several cyber friends by doing just that.
