I used to, starting maybe 15-16 years ago, and I kept it up for a good long while, but I don't get much out of it anymore. A bunch of people decided, for reasons which never made any sense to me, that blogs and blogging somehow ought to be a mechanism for making money, and in their rabid enthusiasm for commerce managed to suck all the life out of the medium. I no longer feel like writing blog posts is an act of participation in a community, because there is no community anymore, so far as I can see.

The web itself seems to be pretty much over, as far as you can consider it to be a community medium, and the death of blogging is just the most visible aspect of that. I still post on my blog from time to time, but it's basically just out of habit, or because I think I might want to find some interesting link again later.
