I hate how they are in the ABOUT section of your profile but not all of them are listed... I can see the first 5 but after that it says +7 yet I think you can hide all of your badges if you choose to but it will not allow you to see all of them if that is what you want (That is not fair!!!)
If you click the 'edit' button for the 'about you' widget (the one with your bio, bday date, etc), there should be a box you can check that lets you display your badges. The badges will show up in the same widget, right above your bio description. I haven't figured out how to edit their order or which ones get displayed, yet, though. Hope that helps!
