Microblogging is an online broadcast medium that exists as a specific form of blogging. A micro-blog differs from a traditional blog in that its content is typically smaller in both actual and aggregated file size. Micro-blogs "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, micro-bloggers post about topics ranging from the simple, such as "what I'm doing right now," to the thematic, such as "sports cars." Commercial micro-blogs also exist to promote websites, services and products, and to promote collaboration within an organization.
Some micro-blogging services offer features such as privacy settings, which allow users to control who can read their micro-blogs, 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.
|“||Blogging has mutated into simpler forms (specifically, link- and mob- and aud- and vid- variant), but I don’t think I’ve seen a blog like Chris Neukirchen’s [sic] Anarchaia, which fudges together a bunch of disparate forms of citation (links, quotes, flickrings) into a very long and narrow and distracted tumblelog.||”|
|“||A tumblelog is a quick and dirty stream of consciousness, a bit like a remaindered links style linklog but with more than just links. They remind me of an older style of blogging, back when people did sites by hand, before Movable Type made post titles all but mandatory, blog entries turned into short magazine articles, and posts belonged to a conversation distributed throughout the entire blogosphere. Robot Wisdom and Bifurcated Rivets are two older style weblogs that feel very much like these tumblelogs with minimal commentary, little cross-blog chatter, the barest whiff of a finished published work, almost pure editing...really just a way to quickly publish the "stuff" that you run across every day on the web||”|
As of May 2007, there were 111 micro-blogging 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 micro-blogging features have been developed. Plurk has a timeline view that integrates video and picture sharing. Flipter uses micro-blogging as a platform for people to post topics and gather audience's opinions. PingGadget is a location-based micro-blogging service. Pownce, developed by Digg founder Kevin Rose among others, integrated micro-blogging with file sharing and event invitations. Pownce was merged into SixApart in December 2008.
Other leading social networking websites Facebook, MySpace, LinkedIn, Diaspora, JudgIt, Yahoo Pulse, Google Buzz, Google+ and XING, also have their own micro-blogging feature, better known as "status updates". Although status updates are usually more restricted than actual micro-blogging in terms of writing, it seems any kind of activity involving posting, be it on a social network site or a micro-blogging site, can be classified as micro-blogging.
Services such as Lifestream and Snapchat will aggregate micro-blogs from multiple social networks into a single list, while other services, such as Ping.fm, will send out your micro-blog to multiple social networks.
Internet users in China are facing a different situation. Foreign micro-blogging services like Twitter, Facebook, Plurk, and Google+ are censored in China. The users use Chinese weibo services such as Sina Weibo and Tencent Weibo. Tailored to Chinese people, these weibos are like hybrids of Twitter and Facebook. They implement basic features of Twitter and allow users to comment to others' posts, as well as post with graphical emoticons, attach an image, music and video files. A survey by the Data Center of China Internet from 2010 showed that Chinese micro-blog users most often pursued content created by friends, experts in a specific field or related to celebrities.
Several studies, most notably by the Harvard Business School and by Sysomos, have tried to analyze user behavior on micro-blogging services. Several of these studies show that for services such as Twitter a small group of active users contributes to most of the activity. Sysomos' Inside Twitter survey, based on more than 11 million users, shows that 10% of Twitter users account for 86% of all activity.
Twitter, Facebook, and other micro-blogging services have become platforms 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 the general user population, with 15% of marketers following over 2,000 people and only 0.29% of the Twitter public following more than 2,000 people.
Micro-blogging has also become an important source of real-time news updates during socio-political revolutions and crisis situations, such as the 2008 Mumbai terror attacks or the 2009 Iran protests. The short nature of updates allow users to post news items quickly, reaching an audience in seconds. Clay Shirky argues that these services have the potential to result in an information cascade, prompting fence-sitters to turn activist.
Micro-blogging has noticeably revolutionized the way information is consumed. It has empowered citizens themselves to act as sensors or sources of information that could lead to consequences and influence, or even cause, media coverage. People share what they observe in their surroundings, information about events, and their opinions about topics from a wide range of fields. Moreover, these services store various metadata from these posts, such as location and time. Aggregated analysis of this data includes different dimensions like space, time, theme, sentiment, network structure etc., and gives researchers an opportunity to understand social perceptions of people in the context of certain events of interest. Micro-blogging also promotes authorship. On the micro-blogging platform Tumblr, the reblogging feature links the post back to the original creator.
The findings of a study by Emily Pronin of Princeton University and Harvard University's Daniel Wegner may explain the rapid growth of micro-blogging. The study suggests a link between short bursts of activity and feelings of elation, power and creativity.
While the general appeal and influence of micro-blogging seem[original research?] to be growing continuously, mobile micro-blogging is moving at a slower pace. Among the most popular activities carried out by mobile internet users on their devices in 2012, mobile blogging or tweeting was last on the list, with only 27% of users engaging in it.[failed verification]
Privacy is arguably a major issue because users may broadcast sensitive personal information to anyone who views their public feed. Micro-blog platform providers can also cause privacy issues through altering or presetting users' privacy options in a way users feel compromises their personal information. An example would be Google’s Buzz platform which incited controversy in 2010 by automatically publicizing users’ email contacts as ‘followers’. Google later amended these settings.
On centralized services, where all of the Micro-blog's information flows through one point (e.g. servers operated by Twitter), privacy has been a concern in that user information has sometimes been exposed to governments and courts without the prior consent of the user who generated such supposedly private information, usually through subpoenas or court orders. Examples can be found in Wikileaks related Twitter subpoenas, as well as various other cases.
Security concerns have been voiced within the business world, since there is potential for sensitive work information to be publicized on micro-blogging sites such as Twitter. This includes information which may be subject to a superinjunction.
Live blogging is a derivative of micro-blogging that generates a continuous feed on a specific web page.
Instant messaging and IRC display status, but generally only one of a few choices, such as: available, off-line, away, busy. Away messages (messages displayed when the user is away) form a kind of micro-blogging.
