CEO is semi-active there, he posts some news from time to time, but dont reads actively and dont answers to every question.
Most postings there are some research results from the medical sector, not how eHealth is developing.
A CEO isn't supposed to talk to the community unless it is major news but I fear that Nikolay is doing most of the work and there is no clear number 2 who could help him.
That is usually the case but there are some CEOs who are trying to keep in touch with investors but you are right, they should have a proper community manager and the rest should make sure they will keep up with their road map.
