I wonder if there's something like Twitter but a feed (RSS or otherwise) of interesting people's blog, YouTube, podcast or creative work?

I feel the value of Twitter would be a feed of interesting people. But 280 characters is just knee jerk thoughts.

Something to easily discover people, like Twitter, whist showing their content, seems more valuable.

Right now, the discovery part sucks. It's possible to find interesting people and sub to the RSS, but not everyone has that (like my blog). Not to mention how spread out content is, someone might release a podcast, or interesting YouTube vid, instead of just blog articles. It's just too much work.
