I use RSS to keep up with podcasts, with a couple webcomics and [so far] one comedian's tour-dates list. I'm hovering around 50 subscriptions, which I feel is "too much" but I'm not sure which great content I should cut; I have a few ideas, but it's in the small single digits against the 50. For myself, I'm likely much better to start slashing at my email. What suggestions do you have on how to "hyper optimize" with that?
