If I have the answer, but it will take some time to type it out, I will hit save after answering part of it (not even a complete part - I hit save after the first line or two).
Then I'll edit it to be a complete answer. (Release early, release often :) By doing this other answers see that someone else is working on it and won't also answer the question (this way they don't cost me points, but it also prevents them from wasting their time, so it helps both of us).
This is only necessary in the more popular question categories.
Also, once you have enough reputation the interface becomes faster and it's easier to race the answers.
That said, I got a bit tired of the race, and semi-retired.
