Microblogging is a form of blogging using short posts without titles known as microposts or status updates. Microblogs "allow users to exchange small elements of content such as short sentences, individual images, or video links", which may be the major reason for their popularity. Some popular social networks such as X (Twitter), Threads, Tumblr, Mastodon, Bluesky and Notes can be viewed as collections of microblogs.
As with traditional blogging, users post about topics ranging from the simple, such as "what I'm doing right now", to the thematic, such as "sports cars". Commercial microblogs also exist to promote websites, services, and products and to promote collaboration within an organization.
