On supporting websites, Gravatars have become a de-facto identity for comment threads and discussions so to carry through the identity to the conference floor is just a logical conclusion.
There is one caveat. Gravatars can now be up to 512×512 pixels. The bigger they are, the better they’ll print. If your Gravatar is a measly 32×32 pixels it’s going to look like a dirty smudge next to the shiny badges of the big boys. Andy has created a handy form for checking if your image is the right size. If not, please upload a new Gravatar before August 14th!
I won’t be at WordCamp this year but after seeing the line up of speakers I’m looking forward to seeing the blog coverage afterwards.
PS. Andy has a new post showing how to create those badges with the help of a PDF library.
