In technology, there was “hashtag,” which is the hash sign added to a word or phrase that lets Twitter users search for tweets similarly tagged; “intexticated” for when people are distracted by texting while driving, and “sexting,” which is the sending of sexually explicit SMSes and pictures by cellphone.
Finalists from the economy included “freemium,” meaning a business model in which some basic services are provided for free, and “funemployed,” referring to people taking advantage of newly unemployed status to have fun or pursue other interests.
“Birther” and “teabagger” made the finals in the political and current affairs section.
