I read quite a lot of blogs, and I do so easily and efficiently with google reader. And google reader also automatically tells me what people I know "share" in their google reader. This is great, I click "share" on blog posts I really like and others do the same. However, even though I know a lot of smart people, only few of them seem to use google reader, and they don't all use the "share" button that much.
Fortunately for me, I have found a way to follow the "sharings" of a lot of smart people who share links and post on FriendFeed. And even more, I can also follow the discussions they have about the links and posts (and participate). I follow a bunch of individual people and I follow some "rooms" where people share stuff with a common theme. Eg.
This is one step up from blogs in sophistication, I think.
