Microblogging

Microblogging is a broadcast medium in the form of blogging. A microblog differs from a traditional blog in that its content is typically smaller in both actual and aggregate file size. Microblogs "allow users to exchange small elements of content such as short sentences, individual images, or video links". These small messages are sometimes called microposts.

As with traditional blogging, microbloggers 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/or products, and to promote collaboration within an organization.

Some microblogging services offer features such as privacy settings, which allow users to control who can read their microblogs, or alternative ways of publishing entries besides the web-based interface. These may include text messaging, instant messaging, E-mail, digital audio or digital video.

Advantages

Twitter, Facebook, and other microblogging services are also becoming a platform for marketing and public relations, with a sharp growth in the number of social media marketers. The Sysomos study shows that this specific group of marketers on Twitter is much more active than general user population, with 15% following more than 2,000 people. This is in sharp contrast to only 0.29% of overall Twitter users who follow more than 2,000 people.

Microblogging services have also emerged as an important source of real-time news updates for recent crisis situations, such as the Mumbai terror attacks or Iran protests. The short nature of updates allow users to post news items quickly, reaching its audience in seconds.
