Nerdbait: How to cite a Tweet in an academic paper, from The Atlantic (h/t saragregory for find)

EMarketer is projecting that Twitter's global ad revenue will reach $139.5 million in 2011, up 210% from $45 million in 2010, the first full year the company sold advertising. Ad revenues are forecasted to reach $260 million in 2012 and $400 million in 2013.

Twitter is readying a new ad product that will for the first time serve up ads to users from company accounts they don’t already follow.

These ads will appear on a user’s timeline; where previously users had to follow, say, @Starbucks to see a Starbucks ad, this new plan will mean users who don’t follow the coffee chain might see an ad for a new sugary drink.
