Here's a common occurrence, at least for me. After searching SO for an answer to my question and finding none, I begin drafting a question to post. With a good title, sometimes I find a solution among the Related Questions, but sometimes not. Then I begin typing away my question, refining and reformulating as I go. Fairly often, by the time I have the question worded just right, the answer becomes clear! Now I close the page or go back since there is no Abort button (which I really think would be nice, but I digress). However, it might be fun to keep track of how often a user goes through this process, only to answer his own question.
More precisely, how often does a user go to all the trouble of typing up a long (> N characters) question, only to discover the answer in the process, and therefore never post the question? Yes, I am aware that some times some people feel it's appropriate to post anyway and then post an answer, but for my part, the answer is often what's left in the box not the question, so I just move on.
I realize this may be hard or impractical to implement, but am I the only one who does this on a regular basis?
