Blog - types & popularity

There are various types of blogs, and each differs in the way content is delivered or written.

By media type
A blog comprising videos is called a vlog, one comprising links is called a linklog, or one comprising photos is called a photoblog

By device
Blogs can also be defined by which type of device is used to compose it. A blog written by a mobile device like a mobile phone or PDA is called a moblog.

Genre
Some blogs focus on a particular subject, such as political blogs or travel blogs.

Legal status of publishers
A blog can be private, as in most cases, or it can be for business purposes. Blogs, either used internally to enhance the communication and culture in a corporation or externally for marketing, branding or PR purposes are called corporate blogs.

Blog search engines
Several blog search engines are used to search blog contents (also known as the blogosphere), such as blogdigger, Feedster, and Technorati. Technorati provides current information on both popular searches and tags used to categorize blog postings.

Blog popularity
Recently, researchers have analyzed the dynamics of how blogs become popular. There are essentially two measures of this: popularity through citations, as well as popularity through affiliation (i.e. blogroll). The basic conclusion from studies of the structure of blogs is that while it takes time for a blog to become popular through blogrolls, permalinks can boost popularity more quickly, and are perhaps more indicative of popularity and authority than blogrolls, since they denote that people are actually reading the blog's content and deem it valuable or noteworthy in specific cases.

The blogdex project was launched by researchers in the MIT Media Lab to crawl the web and gather data from thousands of blogs in order to investigate their social properties. It gathered this information for over 4 years, and autonomously tracked the most contagious information spreading in the blog community. The project is no longer active.
Blogs are also given rankings by Technorati based on the amount of incoming links and Alexa Internet based on the web hits of Alexa Toolbar users. In August 2006, Technorati listed the most linked-to blog as that of Chinese actress Xu Jinglei and the most-read blog as group-written Boing Boing.

It was reported by Chinese media Xinhua that the blog of Xu Jinglei received more than 50 million page views, claiming to be the most popular blog in the world. In mid-2006, it also had the most incoming links of any blogs on the Internet.

Blogging and the mass media
Many bloggers differentiate themselves from the mainstream media, while others are members of that media working through a different channel. Some institutions see blogging as a means of "getting around the filter" and pushing messages directly to the public. Some critics worry that bloggers respect neither copyright nor the role of the mass media in presenting society with credible news.

Many mainstream journalists, meanwhile, write their own blogs -- well over 300, according to CyberJournalist.net's J-blog list. The first known use of a Weblog on a news site was in August 1998, when Jonathan Dube of The Charlotte Observer published one chronicling Hurricane Bonnie.

Blogs have also had an influence on minority languages, bringing together scattered speakers and learners; this is particularly so with blogs in Gaelic languages, whose creators can be found as far away from traditional Gaelic areas as Kazakhstan and Alaska. Minority language publishing (which may lack economic feasibility) can find its audience through inexpensive blogging.
