Well you just watched more videos that have now been deleted than I have. Lets say you watched 100 videos that have been deleted, those are 100 videos that I can never watch, but they still count towards your progress. So that's why you see people with more videos watched than others. I believe that there are roughly 9,000-9,500 currently on the site but I could be wrong. That's a struggle of mine because I can only move forward on the leaderboard if I watch the videos that are currently being added.

Sadly hidden content is where they are preparing the new content on KA. I'm not allowed to share those links publically. If you want, you can email me and I'll send you a few links of extra content. My Khan Academy email is light_runner@yahoo.com (No pressure to email me if you'd rather not disclose what your email is.)

A place I often look is Pixar, Career Profiles, and the AP content. They seem to always be adding new videos there.
