From our friends at WeissComm Partners, a great collection of last year's most important/influential stories. What stories will we be talking about in 2011?
Starting from a list of more than 500 news articles and blog posts, WCG developed a simple algorithm to zero in on the Top 10 stories from 2009. The ranking, highlighted below, considers factors such as the number of websites that link to an article, how many people commented on it, how broadly it was disseminated in Twitter and top social bookmarking sites, and how many websites referenced the article's headline.
Rank Headline Author Outlet 1 Lori Montgomery and Shailagh Murray Washington Post 2 Barack Obama NY Times 3 Danny DeFreitas (Deputy Editor) MSNBC 4 John McKenzie and John Parkinson ABC News 5 Fred Hiatt (Editor) Washington Post 6 Susan Page, Marisol Bello, John Fritze, Mary Brophy Marcus and Liz Szabo USA Today 7 Vital Signs Blog--Contributors Dr. Sanjay Gupta and Barbara Starr CNN 8 David M. Herszehorn NY Times Prescriptions Blog 9 Julia Sommerfeld (Editor) MSNBC 10 CBS News Associated Press

More and more we require sub articles to locate meaningful information that we may have read earlier .With so much available it is difficult to know how to book mark adequately.

Interesting point, Chris. Let me take a look at the original grouping of stories and supporting data to see where this story fell in the rankings. Will update you here.

Given what I saw on the talking heads programs (and the Daily Show), I am surprised that Atul Gawande's article in the June 2009 New Yorker (McAllen, Texas costs) did not make the list.
