I've had blogs before, and having no readers is a little bit depressing for me. It REALLY doesn't seem worthwhile when no one is reading it. The few times I managed to get a link to stick on reddit's r/programming, the blog posts were mostly ignored, then buried and on one I was flamed because people didn't understand it.
Having no readers is a bit of an over-statement. I have some friends who read it occasionally and ask about specific topics, and a few random people who probably glance at it once or twice a week.
Point is, blog's are useful even if only a few people are reading it, because it's just important as a tool for you as for other people.
Might I recommend adding the link to your HN profile's "about" section? It may be of interest to some folks here (at least, I don't think I've been able to go very long without seeing people here talk about economics).
