We made it really, really simple for people to make a blog and put whatever they want on it. Stories, photos, GIFs, TV shows, links, quips, dumb jokes, smart jokes, Spotify tracks, mp3s, videos, fashion, art, deep stuff. Tumblr is million different blogs, filled with literally whatever. All those great, random blogs your friends send you, those are Tumblr blogs. See something great? Reblog it to your own blog.
