How much did ads affect Twitter’s 2010 trends?

Twitter just released a year-end list of top trends for 2010, much as search engines like Google and Bing release their top queries. But it’s a little different here.

Given Twitter’s status as a chattery network of rapid-fire conversations, breaking news stories and pop culture–including, notably, pop-culture phenomena with small, devoted cult followings–dominate the list, called “Hindsight.” Twitter’s algorithm for calculating top trends favors “novelty over popularity,” meaning that a sudden and unexpected spike like the death of a C-list celebrity may ultimately outrank an ongoing major news story.
