I've been a bit lazy in transitioning to MT4 -- I've been happy with the site and haven't really wanted to tackle any possible upgrade issues. But the iMT plugin -- MovableType for the iPhone -- is pretty darn appealing. I'm also testing whether or not I can move some of my Flickr content back onto this site, so it's best to start at the leading edge.

Update: the fancy new interface of MT4 is definitely causing some bugs... (the textbox in the entry didn't load, the page is jumping up and down because I clicked on a menu, etc...)
