I've been paying for newsblur ( http://www.newsblur.com/ ) ever since google reader bit the dust. It's pretty much a direct replacement. Interface has come a long way since day one and is sufficiently slick now (UI, keyboard shortcuts, etc) that I don't really notice it. Highly recommended by a (former) hardcore google reader user. If I recall correctly, got quite a good bit of press here on HN at the time.
Disclosure: I have 2350 feeds in NewsBlur.
