You would think that "no tweet will ever be taken seriously again" as you said, but this thing has had cycles. Every couple of years a new batch of investors gets excited about the stock. Stu starts to say how great things are (then I believe he starts to sell his shares), and then after he leaves everyone burned he goes dark again.
The executive office in Denver (Zen) says they rarely see him, and barely knew who the company was.
I have many shares, so I was really hoping for different outcome this time. But, definitely don't hold your breath.
