Here're some technical ideas for dealing with potentially offensive content:
- Tag "potentially offensive" content for downstream censorship.
- When someone creates an account on Wikipedia they can check a "hide potentially offensive content from immediate view" option, which can be overridden when reading an article.
- As Skyring suggested, a one-time cookie-based splash screen when navigating to a page with "potentially offensive" content, for those not logged in.
- Print versions of Wikipedia could simply include or not include "potentially offensive" content. If both were printed one would be for the squeamish and one for everyone else.
