Quicksilver is by far the best application on my computer. I used to be a LaunchBar user but ever since I found QuickSilver I've loved it! Quicksilver is faster than LaunchBar, much prettier, and has a lot more features. And what's better is that Quicksilver is under rapid development and the creator is very responsive to feedback. And with the recent betas plugin development has expanded Quicksilver even further. So far I've written 4 Quicksilver plugins.

Quicksilver is more than an application. It's a way of life.
