inviting co-workers
Exciting, huh? Dorsey had been working on what would become Twitter for five years by then -it was first called Twttr.
As the story goes, Dorsey elaborated on his idea during a casual Mexican lunch at that San Francisco hotbed of startup DNA, South Park.
Coding began March 13, and eight days later a machine-generated tweet was issued from Dorsey’s account (No. 12):
just setting up my twttr
While this is widely considered the world’s first tweet, Dorsey is adamant that “inviting co-workers” (his Odeo colleagues) was the first, and so is Twitter.
