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, ranking it by recency and popularity. It can therefore be considered the first instantiation of a memetracker. The project is no longer active, but a similar function is now served by tailrank.com.
Blogs are given rankings by Technorati based on the number of incoming links and Alexa Internet based on the Web hits of Alexa Toolbar users. In August 2006, Technorati found that the most linked-to blog on the internet was that of Chinese actress Xu Jinglei. Chinese media Xinhua reported that this blog received more than 50 million page views, claiming it to be the most popular blog in the world. Technorati rated Boing Boing to be the most-read group-written blog.
Gartner forecasts that blogging will peak in 2007, leveling off when the number of writers who maintain a personal Web site reaches 100 million. Gartner analysts expect that the novelty value of the medium will wear off as most people who are interested in the phenomenon have checked it out, and new bloggers will offset the number of writers who abandon their creation out of boredom. The firm estimates that there are more than 200 million former bloggers who have ceased posting to their online diaries, creating an exponential rise in the amount of "dotsam" and "netsam" — that is to say, unwanted objects on the Web (analogous to flotsam and jetsam).
Several cases have been brought before the national courts against bloggers concerning issues of defamation or liability. The courts have returned with mixed verdicts. Internet Service Providers (ISPs), in general, are immune from liability for information that originates with third parties (U.S. Communications Decency Act and the EU Directive 2000/31/EC).
In John Doe v. Patrick Cahill, the Delaware Supreme Court held that stringent standards had to be met to unmask anonymous bloggers, and also took the unusual step of dismissing the libel case itself (as unfounded under American libel law) rather than referring it back to the trial court for reconsideration. In a bizarre twist, the Cahills were able to obtain the identity of John Doe, who turned out to be the person they suspected: the town's mayor, Councilman Cahill's political rival. The Cahills amended their original complaint, and the mayor settled the case rather than going to trial.
In January 2007, two prominent Malaysian political bloggers, Jeff Ooi and Ahiruddin Attan were sued by pro-government newspaper, The New Straits Times Press (Malaysia) Berhad, Kalimullah bin Masheerul Hassan, Hishamuddin bin Aun and Brenden John a/l John Pereira over an alleged defamation. The plaintiff was supported by the Malaysian government. Following the suit, the Malaysian government proposed to "register" all bloggers in Malaysia in order to better control parties against their interest. This is the first such legal case against bloggers in the country.
In the United Kingdom, a college lecturer contributed to a blog in which she referred to a politician (who had also expressed his views in the same blog) using various uncomplimentary names, including referring to him as a "Nazi". The politician found out the real name of the lecturer (she wrote under a pseudonym) via the ISP and successfully sued her for £10,000 in damages and £7,200 costs.
In the United States, blogger Aaron Wall was sued by Traffic Power for defamation and publication of trade secrets in 2005.[23] According to Wired Magazine, Traffic Power had been "banned from Google for allegedly rigging search engine results." Wall and other "white hat" search engine optimization consultants had exposed Traffic Power in what they claim was an effort to protect the public. The case was watched by many bloggers because it addressed the murky legal question of who's liable for comments posted on blogs. The case was dismissed for lack of personal jurisdiction, and Traffic Power failed to appeal within the allowed tim
