Let me begin with my Facebook status update: I JUST PUT ON MY PANTS. THEY FIT WELL.

There are two silent reactions my friends on Facebook might have. Which one do you think is more likely:

a) I really trust Michael's opinion. I wonder what brand of pants he's wearing today, where he bought them, and how much they cost. Does he have a recommendation for a good dry cleaners?
b) Has Facebook stolen my friend Michael's brain?

The more likely answer is b.
