Tumblr is primarily used as a blogging platform for publishing and sharing content. Users are encouraged to choose a specific topic of interest for each of their blogs and submit content based on that interest. Tumblr also has several options to personalize blogs.
Tumblr provides many ways for users to quickly create and share content. These include posting through email, mass editing and tagging, creating audio posts via a phone call, and using mobile apps. As of 2014, Tumblr is available on iOS, Android and Windows Phone. Every blog has a user-friendly dashboard where the owner can modify settings, schedule posts and view the statistics of the blog. While Tumblr is intended for building social networks, users may also use it to create private blogs.
Social interactions are available to connect with other users, such as following blogs, reblogging content and posting comments on posts that allow feedback. Users can also authorize Tumblr to search their Gmail, Twitter and Facebook accounts for friends who already have existing blogs. Users can also send direct messages to other Tumblr users.
To further tailor their blogs to their liking, users can utilize themes, change the blog layout and set up a custom domain. The HTML code of each blog can also be edited or added with custom CSS styles.
