Twitter's stock has been in a nose-dive and now top executives are leaving the company. Twitter is expected to name 2 new board members very soon. Do you think it is a board problem or a "Dorsey Problem"? I believe both Dorsey and the board are at fault. It was a mistake to bring back Dorsey and to allopw him to run 2 companies (Square and Twitter) at the same time. It is a failed experiment. What do you think?
