I'd rather not have my board avatar show in comments I made in the gallery. 

My avatar is for the boards, and so far as I'm concerned the comment areas in the galleries shouldn't be cluttered up with board avatars that take away and distract from the showcased image you are viewing.

In addition to that, not everyone who views the galleries post on the boards or utilizes any other part of the site and I think having avatars next to people's comments looks really, really, really tacky.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
