Many things, really. Contributions include but are not limited to:
 * 1) Editing a page - probably the most obvious of what to do. lol There's numerous possibilities of what can be considered an edit.
 * 2) Uploading images and adding them to a page - though bear in mind: according to Wiki guidelines, duplicate images cannot be uploaded without a good reason.
 * 3) Adding pages to categories - though this one may be a bit tricky as many are already categorized(but still, can't blame a guy for trying).
 * 4) Leaving messages in a user's wall and blog posts - I admit, it's a good way to be sociable, but kind of a weird way to get a badge. But c'est la vie.

These are the only four I can think of, but there's likely more stuff you can do. Though I don't know what the requirements for badges are, I barely take a look at them...so I might be as surprised as anyone here.
