One crazy idea for implementing this would be for everyone to set a flag in their browser that indicates how academically inclined the user is. NERD=0,1,2...9 Then wikipedia paragraphs can just be labeled with the minimum NERD value as a CSS style. The browser can hide paragraphs that exceed your NERD level. If you set NERD=9, you'll see the super dense/academic wikipedia articles.
