@Modemlooper, the whole point of my question was that I have Gravatar’s for every email I own, and not a single one shows up on this site, no matter which email I use here. ITS BROKEN (kinda).
In case anyone’s interested in the fix, only use lower case letters for your email address. I propose that the theme author or who ever’s in charge of it puts a filter on the function that calls gravatar to convert the string to lower-case, as some (like me) prefer to type their names will Capitals.
