Looking at Fever (http://feedafever.com), a standalone server based feed reader. 1st impressions, polished but gimmicky. Lot's of theory about what will improve the experience of using a feed reader but little if any research or other supporting evidence that it works.
To make the most of the Hot list, Fever asks you to make a simple distinction between essential and supplemental feeds. Essential, must-read feeds are Kindling. Supplemental, low signal-to-noise feeds are Sparks. Sparks ignite Kindling raising the temperature of items and links that should not be missed.
If you say so.
