Kottke, the original and still one of the best bloggers around wrote an entry a few weeks ago saying that blogs were dead or ...not.
What seems to work for smaller blogs like this is to link to your blog via Twitter and Facebook posts. That way you can have some longer, essays, but realize most people will only read the 140 characters in the feed. .. It also helps to have snark and lists of the top things you didn't know, but are true.
