I quite like your design by the way. No wasted space showing a list of subscriptions, no social crap, and ~99% of the page dedicated to showing the actual content of your subscriptions instead of flashy UI.
Thanks for your comments regarding the design! I'm going to try to keep it as minimal as possible mostly because that's how I like it, but also so that it can be drop into existing site designs without too much hassle.
Only other comment I have regarding styling is there doesn't seem to be any highlighting of read vs unread items like Google Reader which shows the title of unread items in blue and read titles in black.
Now I need some time to test them all and pick one as my private self-hosted feed reader.
I'd be interested to hear if you have any feedback for yarr - I'll be working on it this week to try to add in the main missing features (managing feeds, timezone stuff etc), and if people think it's missing an important feature I'll do my best to add it.
Thanks for sharing!
