Bjørk!
[As I've mentioned above, Akihiko is on my list, though I do acknowledge that this partly stems from the fact that's I am not a fan of his general approach of aggressively pointing fingers instead of a more balanced discourse. I'm still not convinced the intentions he claims he had for his day one discourse are what he says they are, but I'm not ready to vote for him just yet.]
Awoo!
[Other than that, it'd be much easier to ask me who isn't on my list. The quiet people can be trying not to reveal themselves, while the chatty ones might be using their reasoning as a smokescreen, so anything goes. Aside from Sanada-San, on top of my list is Minato, Shinjiro, and you.]
