Microblogging is a form of multimedia blogging that allows users to send brief text updates or micromedia such as photos or audio clips and publish them, either to be viewed by anyone or by a restricted group which can be chosen by the user. These messages can be submitted by a variety of means, including text messaging, instant messaging, e-mail, digital audio or the web.
The content of a microblog differs from a traditional blog in that it is typically smaller in actual size and aggregate file size. A single entry could consist of a single sentence or fragment, an image or a brief video. Still, its purpose is similar to that of a traditional blog.
Users microblog about particular topics that can range from the simple, such as what one is doing at a given moment, to the thematic, such as sports cars, business topics or particular products. Microblogs provide a short commentary on a person-to-person level, share news about a company's products and services or provide logs of the events of one's life.
