I have signed up and created two gravatars. One for my wordpress.com "persona" (unique email address) and one for my other "persona" (unique email address) on a hosted domain (wordpress install. http://site.gravatar.com/signup
Below are questions that I would like answers to please.
(1) Will wordpress.com members automatically have their gravatar included or will it have to be added?
(2) Will all avatars show on both interfaces or will there be one common interface for gravatar and for wordpress.com?
(3) What happens when it comes to those like myself who have both wordpress.com blogs and wordpress.org installs? How will our situation be handled?
