An occasional downside to Chill Pill is that, since it's essentially a front-end for a Web app, its performance is often dependent on that Web app--if Fever is slow to respond, so, too, is Chill Pill. For example, after clicking Chill Pill's new-feed button, Fever's feed dialog sometimes takes a while to appear.

As a fan of Fever, I've been impressed by Chill Pill--enough so that I've deleted my Fluid instance of Fever and removed Fever's URL from Safari's Top Sites. I really like being able to run my Web-based newsreader in a dedicated application that integrates so well with the service it's designed for, and I'm still surprised that Chill Pill is free. Fever itself may not be for everyone, but every Fever user should take a look at Chill Pill.
