I love Fever. Putting the high volume news sites as "sparks", and the high signal feeds that I like to read everything from as "kindling", gives a great way of seeing trending topics when you have the time, but without seeing a giant unread count in your list.

Well worth the one-time fee and setting it up on my Linode box.

It is a great idea, though a little too over-designed. The concept gets in the way of reading more than it should.
