I'm curious if he even read the article. I was pretty explicit that I use many free products, because they're often better, and many proprietary ones because they too are often better.

I do have one blog on MT and one on Wordpress, and to be honest I'm not sure which I prefer. It's a close call either way. Given what I've heard of Wordpress's scalability issues, I think I'd use MT if I were running a blog with the expectation of large traffic numbers.
