One answer I provided I meant merely as an addendum to what I thought was someone else's perfectly great answer that had a good vote score already. I only wanted to provide a different perspective, and I wanted to add an additional useful answer.
My answer eclipsed the other answer and I rep trained for a few days.
Something similar happened a few days later, but there wasn't another answer. I figured someone else would come in over top of me with a more canonical answer, but even though more thorough answers were offered, my answer got most of the votes.
As a result, I think I learned something about tone. I think I might try to emulate the "Bears" too often in trying to provide an authoritative answer. In one case, I even interviewed a famous expert in order to come up with an answer to end all answers (it got 4 votes). But the attitude I had while writing high-scoring answers was much lighter and I took myself less seriously, I even avoided being complete. To quote Rory, they were "throwaway answers".
But, here's the thing: I'm not sure that my high point answers are good answers, and I don't think that I should make all my answers emulate them. They might speak to the audience and reach some inner curiosity: "I never thought of that!" or "I always thought that was true" or some such, but they aren't the answers I'm proud of.
