According to BlogPulse, politics took a back seat after the national elections of 2004 to discussions about entertainment, technology and natural disasters in 2005. Also, the discussion on the evolution of blogs as a legitimate media channel continued as a key topic within the blogosphere.
"Blogs have emerged as a worldwide phenomenon that touches nearly every aspect of everyday life, commerce, technology, media, entertainment, politics -- even the coverage of natural disasters and news events, such as Hurricane Katrina and the London bombings," said Sundar Kadayam, chief technology officer for Intelliseek, which hosts the BlogPulse.com search engine and analysis tool.
According to BlogPulse there are currently 20,121,008 "identified blogs."
The Cincinnati-based Intelliseek, a marketing intelligence firm, reported in its year-end blog review that Michael Jackson and Britney Spears generated more celebrity buzz than other entertainers; that Boing Boing and Engadget were the two most popular blogs; and "Sin City" was the most popular movie.
Also, bloggers referred to the online encyclopedia Wikipedia for information about "podcasting" and "Hurricane Katrina" more than any other topic or issue.
Which news story did bloggers cite most often -- "That honor fell to an April essay titled 'Unitarian Jihad,' a call for moderation and reasonableness in politics and religion, written by Jon Carroll of the San Francisco Chronicle," according to Intelliseek.
Intelliseek also reported that "blogs also turned serious in 2005, represented by the fifth most-cited blog post (January) from the Committee to Protect Bloggers, which launched a campaign to free two Iranians who were imprisoned for blogging."
