"The great moment of internet history!" hahahahahahahahah
You people need to wake the heck up. Just think for a moment why is this???
Zuckerberg was chatting with an unnamed friend, apparently in early 2004. Business Insider, which has a series of quite juicy anecdotes about Facebook's early days, takes the credit for this one.
The exchange apparently ran like this:
Zuck: Yeah so if you ever need info about anyone at Harvard
Zuck: Just ask.
Zuck: I have over 4,000 emails, pictures, addresses, SNS
[Redacted Friend's Name]: What? How'd you manage that one?
