What's the total of pre-set badges?
38 Badges (as shown on the Badges page) on Meta.
I counted 40 on StackOverflow. They have the Beta and Fanatic badges, so that upped the count. I imagine the Beta badge will be on both SuperUser and ServerFault. I imagine that the Fanatic badge will be available for all the sites, but if they are not at the moment, they will be displayed as soon as someone hits 100 straight days (maybe?).
The tag badges are automatically created whenever someone first achieves 400 upvotes (for silver) and 1000 upvotes (for gold) in a single tag.
