I was wondering if an additional feature in regards to gravatar be added to change the size of Gravatar's avatars from always being 80x80 to the max size of an uploaded avatar. You only need to add s=150 to the Gravatar URL as a parameter (in the query string) to upsize the avatar to say 150px square. Seems simple enough to me to upscale Gravatars
