Yesterday, designer and developer Jason Santa Maria tweeted this awesome little bookmarklet, and I've already used it a good ten times in less than 24 hours. You just drop WhatFont into your bookmarks bar, then, whenever you're cruising a web page and want to know what type they used, click it and it'll let you know.
HTMLers and other smart guys could probably figure this out with style sheets and their fancy tools, but this is a gem for the rest of us.
It works! See?
Cool, huh? In case you're wondering, we mostly use Rockwell, Georgia, and a bit of Courier 'round here.
Grab it here, and post what you find in the comments below!
