Variety, spice, and all that

I should add to the points below that I’m looking to try out Word Press not out of any problems with Movable Type. In due course, I want to try various of the tools; I started on Blogger and moved to MT (but did not upgrade to the latest version because it was likely beyond my own IQ) and now want to try WP. There are lots of great tools enabling this new medium and I don’t mean to slight any of them. Besides, my son is my webmaster and he says he’ll support WP. Gotta do what the boss says.
