Last week the word "tweet" was added to the Oxford English Dictionary. Craig Hockenberry, a principle of the Iconfactory, co-creator of Twitterrific, and iMore hall of famer, gave some background as to its origins on his blog, Furbo.org:

It still feels strange to hear a word I helped create be mentioned over and over again in the media. It's a great word to go along with a great service, and in the end, I'm just happy we're not calling each other twits!

More than just the word "tweet", the Iconfactory and Twitterrific are responsible for the bird and a remarkable amount of Twitter's common branding and popular identity. The whole story is charming and enlightening, and a rare glimpse back at the very incommon beginnings of something that now seems so commonplace.
