We lied. But now you understand this thing. So come on in.
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 391 million different blogs, filled with literally whatever.
Turns out that when you make it easy to create interesting things, thats exactly what people do. All those great, random blogs your friends send you, those are Tumblr blogs. Well help you find and follow blogs like that, and well help other people find and follow yours.
Once you follow a blog, all of its posts show up in your dashboard, just like youd expect. See something great? Reblog it to your own blog. Add commentary if you like. Make it your own. Other people will do the same to your posts. Thats how you meet people here.
Seven post types to get you started. Your brain can do the rest. This thing is yours. Use it however you like.
