reeder app is so good, I'm afraid Im tied to it and have to go with whoever Silvio chooses to go with. But otherwise, yeah newsblur's learning feature seems pretty cool.
Right, I'm in the same boat. I hope Silvio updates Reeder for iPad and OS X to add Fever support.
After so many web services that I depended on have been shut down, I like the idea of hosting Fever myself. Getting to own your own data, no ads, less privacy concerns.
