Earlier quoted context omitted.
Sounds plausible. There are probably many queries required to display a page and Facebook has 2 billion daily active users.
This is how information slowly changes. The original numbers from facebook needed to be taken with a grain of salt. 2 billion a day raises it more. Facebook claims to have 2 billion accounts but no where near 2 billion unique accounts. I don't know what facebook calls an active user but it use to mean logged in once in the past 30 days.
