Twitter CEO Jack Dorsey says that his account suspension yesterday was the result of an "internal mistake." Whoops! I got $5 that says some poor overworked low-level employee somewhere is looking for a new job...one day before Thanksgiving. Attempts to visit Dorsey's account around 6 p.m. PT yielded a standard message indicating his account had been suspended. About 15 minutes later, the account mysteriously reappeared, but instead of the more than 4 million followers Dorsey previously had, his number of followers was pared down to a very modest 142.
