Twitter's Latest Reshuffle Doesn't Inspire Confidence

This week, Twitter pushed its consumer product head, Daniel Graf, into a “special projects” role, choosing to give another executive charge of his responsibilities, according to a person familiar with the matter who wasn’t authorized to discuss it publicly.

Three things make this surprising. First, Graf had just joined the company in April. Second, his hiring had been a sticking point in a power struggle between Chief Executive Dick Costolo and Ali Rowghani, the chief operating officer, which ended with Rowghani’s departure in June. And third, this makes Graf’s replacement, Kevin Weil, the fifth person in charge of Twitter’s product in five years.
