The new Kung-Log was just released, and, if you have Safari 1.0 installed, it now uses the Apple WebKit for previews. The preview pops up almost instantaneously, and it even fetches your style sheet from the blog home page, which means that your previews look more or less exactly like they will look when posted. This is awesome. If you use Mac OS X and Movable Type, you should check out Kung-Log for managing your weblog. (It has some support for other weblog systems — see the Kung-Log page for details.)
