I really don't think bloggers should expect comments. In my experience blog comments fall into three categories. 1. People who want something from the author (notice, funding, what have you). 2. People who think the blogger is an idiot and feel the need to argue with them. 3. Personal friends of the blogger. There are People who actually want to discuss the issue but they tend to gravitate towards communities where they know they'll get intelligent debate (like HN). So unless you're a celebrity and big enough to have a whole community established around your blog you should really feel grateful for no comments. It means people don't think you're an idiot and that you're smart enough to not interact with your friends through a blog.
