Exactly! He is so good example that it is easy to not even notice him being a good example.

There is no "Gwern has an identity he is trying to hide" thought running in my mind when I think about him (unlike with Yvain). It's just "Gwern is Gwern", nothing more. Instead of a link pointing to the darkness, there is simply no link there. It's not like I am trying to respect his privacy; I feel free to do anything I want and yet his privacy remains safe. (I mean, maybe if someone tried hard... but there is nothing reminding people that they could.) It's like an invisible fortress.

But if instead he called himself Arthur Gwernach (abbreviated to Gwern), that would be even better.
