Searchers appear to be interested in any photos, quotes, speeches, and video of those speeches, particularly the "I Have a Dream" speech. They're also busy looking for background on King's assassination and anything associated with civil rights topics. For example, Buzz Log recorded traffic spikes for the phrases "civil rights," "civil rights movement," and "martin luther king day 2006."
The Buzz Log also reports big search spikes on the following people and topics related to Dr. King: Malcolm X, Rosa Parks, Jackie Robinson, George Washington Carver, Harriet Tubman, Abraham Lincoln, the KKK, Jesse Jackson, Frederick Douglass, Nelson Mandela, Sojourner Truth, Booker T. Washington, Gandhi, and Thurgood Marshall.

Yahoo! also has something called the Tech Buzz Game, a fantasy prediction market for high-tech gadgets, concepts, and trends. This feature enables people to actively participate in predicting the technologies we will be searching the Web for in the future. It's a pretty cool search feature and one that promotes active consumer engagement. We like. See for yourself: http://buzz.research.yahoo.com/bk/
