On my 1440p display avatars are approximately 68x68 pixels. This is Too Small, and frankly we should be against Twitter's War Against Legible Avatars.
Something Awful by comparison allows 180x180 sized avatars, and they are works of art.
the smaller an avatar gets, the less I'm able to recognize people by their avatars. and because i have a hard time with names this makes sites just feel more anonymous
