Occasionally, there are crazy question-answer ratios because of users who mostly answer questions - these people obviously have tons of knowledge they can share. With this in mind, since we want to increase the number of questions asked, I thought I'd point out that self-answering is encouraged by the SE system. So if you came up with a nice solution for a pesky problem - share it. If you thought of a piece of advice you'd give to first-timers - share it. Everyone else will appreciate it, I assure you.
