People do read it. I mention things in conversation and people say "I know, I've read your post", so that's cool. People also email me about my post, or mention them in unrelated emails.

I treat my blog as a sort of extended dating profile or resume. It's extended in both scope and completeness, attracting all sorts of people for all sorts of purposes, and telling them much more about me than a mere bio. It's a search query for other interesting people, as someone else put it.
