Many companies think that increasing transparency will help them win the hearts of their customers. But for mega-bank JP Morgan, widely seen as one of the actors to blame for the recent financial crisis, that was the absolute wrong choice. The company heavily promoted a public Q&A session on Twitter in November using the hashtag #AskJPM. Obviously expecting softball questions, the bank instead got a titanic stream of hilarious tweets mocking them and pointing out their predatory practices, all using the hashtag that they paid for. The Q&A was cancelled before it began and Morgan crept back into the shadows.
