Quicksilver (the app, not the book)

So I see Simon Willison raving about Quicksilver, and my first thought is “Aha, someone else has read Stephenson’s latest.” But no, Simon is referring to a LaunchBar-like application which is free, and — if the blog hype is to be believed — better!?! I’ve downloaded the application, and I’ll try to use it in place of LaunchBar over the next few days. Follow the link to Simon for other opinions and a tutorial — it’s necessary.
