For various reasons I've moved most of my blogging to Plecebo.org. Just an update.
Smashing magazine wrote an article up on the top 10 web blogging engines. http://www.smashingmagazine.com/2008/08/29/10-weblog-engines-reviewed/
I have a special place in my heart for Drupal (this site runs on drupal if you couldn't tell). Mostly because of its tight integration with a taxonomy, and the incredible versatility of the overall package. I've used most of the top 10, they are all fun to play with, and great ways to learn stuff about what makes the most sense to you when setting up a website.
Ok Maybe it is not that simple:
Example: 25% of the visitors we track at Squidoo use Firefox, which is not surprising. But 50% of the people who actually build pages on the site are Firefox users. Twice as many.
This is true of bloggers, of Twitter users, of Flickr users... everywhere you look, if someone is using Firefox, they're way more likely to be using other power tools online. The reasoning: In order to use Firefox, you need to be confident enough to download and use a browser that wasn't the default when you first turned on your computer.
