My ideal social feed (which neither Warpcast or Twitter implements yet):
- smart sort of people I follow, plus some outside recommendations
- track what I've seen, and avoid reshowing on subsequent visits
- BUT also let me access a "history" of what I've seen recently, for when i want to re-engage after delay

Twitter is really good at tracking what I've seen, and not showing it again. Too good. Makes it hard to go back to something you saw recently.

Warpcast doesn't seem to remove seen content as well (at all?), and so i often run into stuff I've read, and bounce, even though i haven't actually read everything relevant
