How can I stop writing such long answers?

I just get involved in these questions, and my mind goes from one thought to the next, and I’m just writing it down as I think it, and before I know it, I’ve got ten paragraphs. I enjoy doing the thinking and writing, but I know a lot of people won’t read it because it’s too long. I know that, because I do it, too.

In truth, I don’t expect to be able to change, but I do feel fairly alone in this, so everyone else must approach answering questions differently. What are you doing when you answer questions? How do you go about it?
