I'm not sure what kind of questions you normally have, but I didn't really have much trouble getting answers from StackOverflow. It's no accident that when Google "sorts through the unbelievable chaos of the entire open Web to bring up the most relevant answer to any question on any topic in a fraction of a second using the latest 21st Century search algorithms", the first link is almost always StackOverflow ;)

Also I think it's pretty impressive that Joel managed to make the website run smoothly on a vintage 486.
