I am contacting you because you seem to care the most about Categories. I have just checked the "The World of Math" and was amazed at the number of Categories. You can see them here http://khanacademy.wikia.com/wiki/The_World_of_Math. I don't know what to do other than get rid of them all or cut back (which will be a lot more time consuming than getting rid of them all). Maybe you have a better idea.
