I cannot speak for anyone, especially Mark, but it is entirely possible (my OPINION ONLY) that he trusted his social media person to do the common thing, which is tweet often and keep people excited about the company -- without providing much 'specific guidance'. Maybe he hired wrong, or didn't monitor the situation as well as he could have. As mentioned, he was busy trying to manage the lab business. There are surely some holes in this fabric, and questions do exist. We all need clarity, but the process drives the release of the info. For those of us who have held in there, it is more exercises in patience.
