I would really like to see the concept of an image board divorce itself from Japanophilia/otakuism.
So 5chan required registration. So what? Who cares? Nobody was forcing you to go there if you didn't want to.
Furthermore, the 5chan-idlechan war (or whatever it was) was unnecessary, unproductive, self-destructive. Let's not let stupid stuff like that happen again in the "community." I think Wakachan is a step in the right direction on that front.
