OK, after this ringing endorsement from Cory Doctorow, I have to re-evaluate Shrook. I wasn't too impressed with 1.0 but 2.0 sounds cool.
My RSS reader of choice, Shrook, went 2.0 this morning. After five or six hours of using it (couldn't sleep, friggin' jetlag), I am in love. This is the best UI overhaul I've ever seen (the old UI was pretty good too), a completely unexpected redesign that nevertheless managed to make this app that I use all day, every day, into something five times more useful and stable than it had been the day before. I like this punctuated equilibrium stuff.
