My wife’s last name is Lago, and she’s of Italian descent.  This week Facebook started mysteriously displaying all non-user-generated website copy in Spanish.  She never asked for it, and has also clicked a “not interested” link they’ve displayed when prompting her if she wants to continue her FB experience in espanol.

On her computer I just typed in “Facebook.com” to check something and saw the login screen above.  FB is evidently not deterred by her user preferences.
