IMO the websafe -> webfont transition generally looks crappy. You get a brief window where you see the plain font, you start reading, then all the text changes size ever-so-slightly, which moves the entire page around. Jarring. At least as bad as having a bunch of images that aren't fixed size that reorganize the page as they load.
Absolutely agree :) Add in a social-plugin blocker (if you're not a disable-js person), and the internet moves like 3 times faster. Just preventing e.g. someone's twitter feed from loading often makes the page respond a couple seconds sooner, which is really unforgivably bad.
