No, I haven't, for two reasons. I don't think it's a good idea for retail investors to keep our hardworking CEO from the tasks at hand with a barrage of questions. I broke it down, once before, by time and costs. If he gets 30 emails a week and spends an average of 2 minutes on each, reading and responding, that's an hour a week, minimum, which, in my mind, is way too much.
The other reason is that I don't consider emails or tweets to be satisfactory forms of investor relations communications. The idea should be to reach out to all current investors and aim to attract new ones, for which a larger megaphone is needed.
