An article by Jason Clarke of Download Squad about ReaderMini:
I've retired ReaderMini. In it's place, I suggest trying the new iPhone version of Google Reader if you are looking for something similar.
What was ReaderMini? ReaderMini was a multi-pane, fully functional version of of the Google Reader interface, performance-optimized for mobile devices like the Nokia N800/N810 Internet Tablets and the iPhone. ReaderMini was featured in DownloadSquad, jkontherun, atmaspheric endeavors, LifeHacker, and The Official Google Reader Blog.
Users of ReaderMini: Thanks for the ride! It was fun!
