Reddit does a good job surfacing quality content, especially in the domain of art and design. There's several science and space subreddits as well.

Very few ppl can blog consistently enough to warrant an RSS feed -- you need an aggregator of some kind.

Reddit also got too sensationalist for me. Sure, everyone tells me 'choose the right subs', 'trick the algo, make it work for you', but I shouldn't have to, right?
