Problem with those themes is that you may have to re-edit the entire blog modifing the post-format of the posts and then, moving away for any reason to another theme, you’ll have to use one that uses them too.
Anyway it’s a cool new theme and I can’t wait to see which future customizations of it will take us (like some twenty-eleven did)…

Yep, vingt douze is really nice I think, but the social buttons bar looks weird on this home page!
