For me, it's Flipboard. I like how you can choose specific websites, or aggregate feeds based on topics. I also like the page flipping gimmick, though I think more sites need to support that. Oddly enough, I also pair it with Pocket, which I use for sites that I *really* want to read as I am assured that I won't miss anything by what goes into it. With Flipboard, I use that more for browsing vs Pocket which I use for subscribing.
