How to run a blog...

I was having a discussion with Joe a few days ago, and he asked me what he should do when people make comments that ask questions.

My current approach is to look at the question and try to decide whether I should do a new posting on the topic, or whether I should just add a comment, but I realized that I don't know whether most people go back to the comments to look for answers or not.

If you have an opinion on what you think works well, feel free to comment about comments in the comments section of this post on commenting on comments.
