USA Today: On Tuesday afternoon, Jack Dorsey, in a hoodie and beard, spoke to Wall Street for the first time. His hotly anticipated remarks came during the company’s quarterly earnings call with analysts, his first since returning to Twitter as interim CEO. Before the call ended, Twitter’s shares plunged on straight talk from Dorsey and CFO Anthony Noto: Twitter is facing a dramatic turnaround that is going to take “considerable” time before the company sees any “sustained” growth.
