Steve Pilgrim (no relation) asks: Am I correct in saying Mark Pilgrim has 11 MovableType themes?
No. I have 1 MovableType theme and a few lines of Javascript that dynamically swaps the CSS. The HTML never changes. This means I don’t need to publish 11 copies of my site just to get 11 themes; I publish 1 copy, and let you decide how you want to read it.
Joe Gregorio has a similar CSS-based style switcher on his Radio site. There are one or two caveats to be aware of, but it’s quite doable: he’s doing it. Ask him for details.
