I support this video reference library. I was just casually going on about "that time there was an evil snowglobe" and realizing that needs more context.
Another thing that would help for people like me, if you're feeling really generous to your audience, is a Pop Culture Reference Library. There are so many people here from really similar versions of Earth that those references tend to lead pretty strongtly, and those of us who don't share those references end up being all "When were the Star Wars? Did you fight in them?"
