Tumblr is a blogging platform that allows users to post text, images, video, links, quotes, and audio to their tumblelog, a short-form blog. Users are able to "follow" other users and see their posts together on their dashboard. You can like or reblog other blogs on the site and other users can do the same to your posts. As your blog becomes more popular your tumblarity will rise. The service emphasizes customizability and ease of use.
Tumblr’s emphasis is on customizability and ease of use—it only takes 30 seconds to sign up. The “like” button, which lets you tell a user you like his or her content, and the “reblog” button, which easily reposts content from another tumblelog onto yours, provide positive feedback that has given Tumblr an 85% retention rate, compared with 60% for Twitter.[citation needed]
Users "follow" other tumblelogs, much like on Twitter, and their updates appear in one stream on the Dashboard. This is the interface where users can like and reblog posts, as well as the buttons to add content to their own tumblelog. Other tumblelogs the user maintains appear on the right, along with statistics like tumblarity.
