The point still is good CEOs of small companies make themselves available to shareholders through a variety of avenues because it is a large part of their job to do so. Availability builds credibility and trust and assists in raising capital when it is most needed. Certainly you don't believe he has the responsibilities of a normal CEO because I don't see it.
Holding shareholders meeting every three years, never returning phone calls or emails, not doing conference calls, and only doing pathetic and repetitive shareholder updates that never answer the real questions isn't enough. If he can't do the job in its entirety, he should quit.
It's not like his plate should be full based on ERHCs low level of activity. What is he doing on a daily basis to earn his paycheck?
