When I switched from GreyMatter to Movable Type I felt like a whole world of options had been opened for my blogs, though the interface with all its tags and templates made my noggin ache.
Now that I've made the leap to WordPress, I feel I've lost some of the options (not as many plugins, etc.). But, I can BREATHE again. No rebuilding. No futzing with dozens upon dozens of tags.
I built this blog, from sketch through blog setup and code-grokking to tweaked CSS and xHTML, in two days. I had never touched WP before, and I got it working with a bunch of my hacks, in two days--including graphics, typography, coding... One template makes so much different.
I so love WP.
Anyway, if you'd like to check out the site, QuarkvsInDesign.com, The authority on the war between the desktop publishing giants, is completely ported over to WP.
