Facebook: Negative Externalities

I am in the BC lounge of Airfrance in Paris and had to wait 35 minutes to find an empty computer. They were all taken by people using Facebook. The demographic of FB seems to be changing very rapidly. It started with teenagers and people in their 20s, but all users here are in their 40s to 60s.
PS
It is iincredibly difficult to type with an AZERTY keboard
