I've been doing this blog since June of 2002 - if you go back to that first post, it's clear that I had no idea where I was going with the blog - I started it up as a multi-author blog (yes, the Silt server has support for that). Since then, I've been posting regularly - it's been 1459 days, with 8254 posts - that's between 5 and 6 posts a day over that time period.
The interesting thing (to me, at least) is that I'm not tired of it, and I don't see it as a chore. It's still fun, and I'll keep posting as long as it's fun. Besides, there's always something new showing up in my aggregator that makes me want to go off on a rant...
