Rosen sent an errant Tweet this week on seeming corporate pressure involving a subsdiary of AOL --- what he calls "a serious error" --- and he has not only corrected the 140-character mistake but provided an extensive chronology of its pathology.
Before Rosen could correct, his Tweet had spread to a six-figure audience. He found undoing the mess problematic, in particular the weight of making a mistake with his professional credentials behind him.
His case study of his foul-up is an excellent example, though, of how to thoroughly explain how a mistake was made and his thinking along the way. Rosen has Tweeted 15,000 times, but this acknowledgment does nothing to take away from the contribution he has made. If anything, it enhances it.
