I had an idea about this just today: What I want is to be able to quickly save things off without cluttering up tabs (like a "read later") but be periodically reminded what's in there. My thinking is a daily digest pulling a random sample of the saved articles, with quick actions to either leave things on the pile if I'm still interested but still don't have time to read or to remove them if I've lost interest.
Anyone know of anything like this?
