Gotta be honest: I don't have to spend more than 5 minutes on Facebook to dissuade myself of the hypothesis that, on average, people are feeling constrained about what they're saying.

Pretty good example of selection bias. The people who are concerned are not going to be posting on facebook.

Then we would expect posting on Facebook to go down, yet Facebook's user count keeps going up.

You can categorize people into careful and not careful. Posting goes down for the careful, but stays high for the not careful.

The total amount of posting doesn't go to zero because not everybody is in the careful category.
