There's currently no support for gravatar, it would be nice to have it.

It's probably not something we would add everywhere in retrospect, since there are accounts that probably don't want to reveal their emails (and I like the frogs). Maybe it could be something you could optionally turn on?

Yeah, enabling it by default would not be wise. Having an option to turn it on would be great.

Also thanks for clarification that it's a frog :)
