It bothers me too, and I followed up with him about that. But it also bothers me that he hasn't said a word about what those things are that he's been working on. Any other public company tells those providing the company money details and updates.
That is the only message I have ever sent him, the last, and I thanked him for taking the time to reply. He said, "my pleasure."
So please don't rope me in with the peers here who constantly send message after message. I understand how obnoxious that is, but I also understand that there is SO much - that we have discovered on our own by DOING our own DD- that he could have easily put into a PR and kept the share price slowly and consistently rising.
