I think Facebook will be pressured to add controls for users to limit the length back in history that different groups of people will be able to browse your Facebook timeline. Currently, anyone can browse my timeline's entire history on Facebook pursuant to my privacy restrictions. But, do I really want my next girlfriend to be tempted to browse the last five years of my Facebook timeline?
I might personally want to browse all ten years of my Facebook Timeline, but I might want my friends only to be able to look back 3 months. Maybe I'd allow close friends and family to browse one year back. But, I only want to show one month of history on my public timeline, or none at all.
The creepy thing is that advertisers still can electronically datamine/browse your entire timeline and everything Facebook knows about you.
