Theme developers will now have access to a cool new starter theme that the WordPress.com theme team will be using on a routine basis when developing new themes. Not only is this great news for ALL theme developers, but how they are going about it makes me think they are also using this opportunity to experiment with GIT instead of working purely with SVN. I think some would argue that this is what the default theme should have been like within WordPress from the beginning but looking at how successful Twenty Ten has become, perhaps it was’nt such a bad idea.
