Tumblr is a blogging platform that allows users to share life stories, photos, videos, and quotes. It has over 30 million blogs with nearly 11 billion total posts. While Tumblr allows users to express themselves and connect with others, publicly sharing content opens users up to security risks. Its simplicity, ease of "reblogging" others' posts, and user-friendly interface have contributed to Tumblr's success. This particular Tumblr blog has over 24,000 monthly visitors.
