With 1.55 billion monthly active users, Facebook might seem like an unapproachable juggernaut -- a monolithic corporation run on algorithms and data.
In actuality, it's a bit more hands-on than you'd think. In the first installment of "People Behind the Internet," we take a look at Facebook's Tag Suggester, Paul Zuckerberg (no relation).

Keep up the great work, Paul -- we really appreciate it.
