As long as you've read up on the subject beforehand, their forums are also really helpful. A few times, I've asked a question on the Ubuntu forums and been met with dead air, but while the people on the Arch site can be a little short with people who ask questions before searching and reading, if you obviously have, they're more than helpful.

Asking without searching first is disrespectful against users of that forum who spend time to answer questions. It's a little bit like saying "Instead of wasting 30secs of my life to search and try on my own, I'll waste 30secs of yours." Personally, when someone asks something.. and I can paste their exact question and get a well done tutorial on the subject, I don't feel like answering. For a total beginner, obviously, that's different.
