Obama 100 days - Obama 100 days

Although President Obama himself has not talked much about using his first 100 days as a benchmark of his administration's progress, that hasn't stopped the media from treating the milestone as a cross between Super Bowl Sunday and a sighting of Halley's Comet. Thus, the Buzz this weekend was filled with 100-days content of every stripe: a scorecard of campaign promises, quotes from the period, key events, analysis, more analysis, opinion, an NPR series, video, and stuff emanating from the Michelle Obama industrial complex. With the president's poll numbers so high, you can't blame everyone for piling on, perhaps. But still, if the base-10 number system weren't so widespread, we'd probably think of the upcoming 100th day as something more prosaic, like "Wednesday."

Bea Arthur (1922–2009)
The Bea was buzzing after news broke that the irrepressible Bea Arthur had passed away; the actress was one of the top searched-for people on the entire Yahoo! network on both Saturday and Sunday. Arthur won Emmys as the title character in "Maude" and later as Dorothy Zbornak in "The Golden Girls." Both shows are considered groundbreaking, "Maude" for dealing with issues related to the feminist movement (including, most famously, abortion), and "The Golden Girls" for focusing on the lives of female seniors. Among the copious material on Arthur in Buzz: Salon's "Remembering Bea Arthur," Entertainment Weekly's "Golden Girls" oral history, and a New York Times video retrospective, which includes a pretty outrageous "Sex and the City" parody.

Swine Flu
On Saturday, the World Health Organization declared the spreading swine flu a "public health emergency of international concern." Mexico, the epicenter of the outbreak, has suffered dozens of deaths with a suspected link to the virus. In the U.S., milder cases have been confirmed in a handful of states. In both Buzz and on Yahoo! Search, "swine flu symptoms" is the No. 1 related query; you can read up on those and other facts about the disease on the U.S. Centers for Disease Control information page. And Yahoo! News will be providing up-to-the minute coverage.
