AskReddit asked recently: If you could only give an alien one thing to help them understand the human race, what would you give them?

At the time I had no good answer. Now I do. I would give them Charlotte Lennox's write-up of how MsScribe took over Harry Potter fandom (warning: super-long but super-worth-it).

Ozy informs me that everyone else in the world read this story five years ago. Maybe I am hopelessly behind the times? Maybe all my blog readers are intimately familiar with it?

If not, read it. Read it like an anthropological text. Read it like you would a study of the Yanomamo. No, read it even better than that. Read it like you would a study of the Yanomamo if you knew that, statistically, some of your friends and co-workers covertly become Yanomamo after getting home every evening.
