Why would you take a highly-skilled engineer whom obviously enjoys what he does and make him a Community Manager? That is one of the most logic-defying things I have seen on these forums.
As for your comments about Arthur, I think they're unwarranted as he is obviously enthusiastic about the Odyssey expansion as it is a significant milestone for Frontier & Elite Dangerous. I have no objections to people being enthusiastic about what they're working on (even though it is an alien experience for me) and certainly don't begrudge them showing that enthusiasm.
Well not exactly, but information of that type is the most interesting stuff to hear. Instead of being told directly how good they are you can infer that from what they say.
Enthusiasm about the game is fine... not sure that's what they're doing there though. Have a listen to the latest one.
