When was the last time (if ever) 10% of living Americans had all read the same book?

Knowing that 50.52% of the USA are women, I could safely say that 50.52% of the population in the USA has read "Fifty Shades of Grey"

If my psychiatrist was cheaper, I wouldn't have to resort to Farcaster.

The only exception. In another era you would have been interviewed on TV.

I know many many more women who have not read it than have. I went to the first movie as a ‘women’s event’ and there was a lot of laughing as was so awful.
