Nick Bilton, who wrote Hatching Twitter, a book I’ve recommended in the past, writes for Vanity Fair about the current state of Twitter:

If these expulsions sound like murders, that’s likely because many of them were committed with the same behind-the-scenes planning and mastery. In every instance, the man who was knocked off had no idea who was behind the coup that led to his demise. In 2013, after the publication of my book Hatching Twitter: A True Story of Money, Power, Friendship, and Betrayal, I was greeted with effusive (or enraged) phone calls, text messages, and e-mails from co-founders, board members, and senior employees who were excited to finally learn the true identities of their tormentors. I still occasionally receive calls from people inside the company asking me for information about a recent firing.
