I am (in part) attempting to address this discovery issue with http://hubski.com. It is a de-centralized aggregator in that submissions are public, but there are no shared pages. You get the content posted by people you follow, but also the content that they decide to share with you (not unlike a retweet). Instead of votes, posts propagate via shares.
There are also tags, which may be followed as well that are usually topical. That helps 'outside my feed' discovery. Also, you can select a certain amount of external posts to filter into your feed for some serendipity. Finally, you can ignore specific users and tags to control for what type of external posts filter in.
We aren't huge, but we've got a pretty eclectic range of content.
Using this model, bloggers and content creators can post their own links. If people aren't interested, they simply won't see them. -There are no community pages to be polluted. IMHO shared feeds are key to the decline of these types of communities.
