Currently my RSS feed consists of ~1600 feeds and most of them are art accounts on ArtStation, DeviantArt and tumblr, and YouTube channels. I also have regular news, science and tech news, Blender news and blogs, several webcomics (Pepper & Carrot, xkcd, SMBC, Sarah's Scribbles, etc), some miscelaneous blogs (like Wait But Why, Today I Found Out and Picture Of The Day), lots of FOSS projects blogs and release pages, some art blogs, and many LEGO builders flickr accounts.
I think that's about it :grinning face with sweat:
