Part of the downside of posting frequently is that people come to expect it, and if you don't post for a day or so (or in the case of the people in this article, a few hours), people worry about you and think there's something wrong.

I remember another blogger years ago (when we were still calling them journals) who told readers something like: "If I don't post every day, it doesn't mean there's something wrong. It means I'm having a life, which is a good thing."
