Facebook’s 16 year old mistake?

Arthur Le Meur, via his Dad, Loic:

My 16 years old son Arthur first told me “I will delete my entire Facebook profile and create a new empty one when they launch Timeline.” He got so scared that his current friends would see all his posts and pics since 2009 that he somehow managed to activate his account as developer (by creating a fake app I think, I guess it’s a start), activate timeline and then he found he could hide it all.

Here is Facebook’s mistake: considering that everybody will want to expose all his past by default.

Isn’t it… amazing… that every time Facebook has a default position it’s to assume that people will want to expose more?
