Micro-blog

Microblogging is a broadcast medium that exists in the form of blogging. A microblog differs from a traditional blog in that its content is typically smaller in both actual and aggregated file size. 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. 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 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.

The first microblogs were known as tumblelogs. The term was coined by why the lucky stiff in a blog post on April 12, 2005, while describing Christian Neukirchen's Anarchaia.

Jason Kottke described tumblelogs on October 19, 2005:

However, by 2006 and 2007, the term microblog was used more widely for services provided by established sites like Tumblr and Twitter. Twitter for one is especially popular in China, with over 35 million users tweeting in 2012, according to a survey by GlobalWebIndex.

As of May 2007, there were 111 microblogging sites in various countries. Among the most notable services are Twitter, Tumblr, FriendFeed, Plurk, Jaiku and identi.ca. Different versions of services and software with microblogging features have been developed. Plurk has a timeline view that integrates video and picture sharing. Flipter uses microblogging as a platform for people to post topics and gather audience's opinions. PingGadget is a location-based microblogging service. Pownce, developed by Digg founder Kevin Rose among others, integrated microblogging with file sharing and event invitations. Pownce was merged into SixApart in December 2008.
