Please do not waste the CEO's time with questions that can be readily answered on the board (or a quick check on wikipedia for that matter).
It is rare and a potentially valuable resource to be able to get responses from the CEO as we have been able to. But if that is wasted and abused by sending him a constant stream of questions that could be very easily answered from other sources he would very appropriately stop resounding to emails from investors, IMHO.
Frankly, too many and too frequent suggestions that one "just email the CEO" can begin to border on a variation of a "denial of service" attack.
