It looks like in Ponder, when you answer a question, a mail should get kicked off to the Question watchers and a feed story published, however inspecting with phd taskmaster shows that getContent is failing on email. It appears that getAnswer isn't populated, presumably that the mail worker is a separate spin up and the Answer never gets set in the QuestionEditor.
What's the "correct" fix here? Move Answer mail generation to the AnswersEditor? (seems correct if you consider replies to this mail going to the Answer and not the question)
