"We added Buffer support to http://www.rivered.io from day one! You mention competition and innovation but a lot of these feed readers are fundamentally the same as Google Reader. Rivered tries to do things a bit differently - it's a 'River' of news instead of an inbox. It's a bit like Twitter in that respect really; you dip in and out of the content you're interested in without the pressure of unread item counts or whatever." - Jalada
