My problem with are.na right now is that I can aggregate stuff but it's harder to reference and go back. Kinda like bookmarks. I'd almost want a digest of stuff in there or easier findability.

Do you browse the Feed (are.na/feed) page? This is made up of channels + people I follow. Usually I'm on the "Explore" page but the feed is sometimes helpful. Also I really like the emails I get every Sunday showing me a few random blocks I've saved, etc.
