What subjects are you interested in that I don't blog about?

And are there things that I don't blog about that you'd like to read about here? Basically, I'm seeking reader feedback to help me answer someone else's question, but I'm also generally interested in the answer myself.

MORE: People keep answering the second question and not the first. Seriously, my reason for this post is that I'm filling out a survey and one of the questions is about the interests of my readers! I can't just presume you must be interested in whatever I'm interested in. Presumably, there are big areas of interest that I don't touch on. That's what I'm trying to get. I'm not looking for new ideas of things to blog about and not setting out to revamp this blog or anything like that. I should never have thrown in that second question. I'm doing to do some striking to make this clear.
