The war in Iraq was the subject of the most news links shared by bloggers during the week of Sept. 6-10, while a report on Mashable about The New York Times Co. chairman Arthur Sulzberger Jr. saying he expects to stop publishing a print edition of The New York Times in the future was the most-Tweeted news link, and the most-watched news and politics video on YouTube was an episode of YouTube-based The Philip DeFranco Show, according to the Pew Research Center’s Project for Excellence in Journalism’s New Media Index.

The ongoing conflict in Iraq accounted for 25 percent of news links shared via the blogosphere, and it was followed by: news about the White House of President Barack Obama, including rumors about chief of staff Rahm Emanuel leaving the administration and the Oval Office rug, at 22 percent; a story from the Los Angeles Times about the possibility that a school named for former Vice President Al Gore was built over toxic and contaminated soil, at 12 percent; two 2010 election stories from The Washington Post, at 11 percent; and the plan by the Rev. Terry Jones to burn the Koran on Sept. 11 at 10 percent.

Sulzberger’s vision of permanently stopping the presses accounted for 17 percent of news links shared via Twitter, and it was followed by: another offering from Mashable about abducted Japanese journalist Kosuke Tsuneoka using a captor’s cell phone to Tweet his location, at 15 percent; the Koran-burning controversy at 13 percent; several Google-related stories, including those on new search feature Google Instant, at 10 percent; and a report that Apple was lifting its ban on Flash apps for the iPhone, at 7 percent.

The Philip DeFranco Show was followed on the list of most-viewed YouTube news and politics videos by: footage from the Pacific Sun cruise liner in very heavy seas; a video about the end of the summer by German comedy group Die Aussenseiter; New Jersey Gov. Chris Christie responding to a question from a teacher at a town-hall meeting; and an Italian video of a girl dying due to a practical joke (since removed from YouTube due to a terms-of-use violation).
