When I have asked questions here, it's because I can't find what I need Googling or checking manuals etc. It does take more time to get an answer here (at leas on the not so "big" topics) than it takes me reading a tutorial.
And of course when posting from Norway, I might have to wait a day or so for the people living in USA or Australia to wake up or come home from work...
Edit (about "simple google searches"):
Quite a lot of questions asked here can answered by a google search, by people who understand what they ask for. I've answered some questions (even on topics I know very little) by searching google, because I understood what they wanted even if they didn't know the terminology. E.g:
Q: "I want that sort of thing where you have these numbers under a list and you can click on it and get a sort of page",
A: "Oh, you mean pagination. Theres a few good plugins here [google search link], and this one [specific plugin link] is good..."
