I've had no expectations for explanations for board member departures. I've stated as such. Employee departures are always confidential as to the reasons. I've made this argument a couple of times in the past month to those asking for an explanation. That's why I'd like to see the 10Q, even though it will not have info about previous employees, the numbers still tend to tell a story.
As for me, I've got my shades on! ;)
