Dear Twitter,<p>They&#x27;re going to let me be CEO again, but as part of the deal I had to fire a bunch of people. Mostly engineers since I&#x27;m told there are many of them who cost too much and don&#x27;t seem to impact the top line. Please let&#x27;s all be nice about the whole thing, so it doesn&#x27;t turn into a PR disaster.<p>Jack
