Whatever you think about Facebook, it is not irrelevant to the vast majority of people. What was the pressing issue it was solving? Even the personal computer was not solving a pressing issue at the time. New products create the demand for it and the influence of it only makes sense in retrospect.

We solve huge problems by first solving small ones and laddering up.
