Digg annouced that it has taken the new categories off of beta, and users can now look at stories in the previously beta’d categories without having to register. To date, I’ve been relatively impressed with the additional stories that Digg users have included in the new categories - granted, not all of them are winners, and some of the newer categories (like World and Business) seem to be less beefy than others (like Entertainment), but all in all, its a handy tool to have.
