How many CEO in the global business ecosystem would take time to reply every question about its project? There are very few. And thats what just MITOSHI CEO been doing. I think it takes tremendous efforts to put the community together while making sure developers do their job.
I think that the average CEO is only one, but if a lot of it will make it better, but the work must also be shared for each choice that will be made. I think personally.
I have seen few project where CEO was actively involved with public, project followers, some even held multiple AMA session and wrote some technical stuff related to projects. All those project are very successful. This gives idea how important CEO's role is.
