Marc Zuckerberg in a Wired interview:
We talk about the Moore’s law of sharing, but we never meant that all this will happen on Facebook—it will happen in the world. Our challenge is to make that happen on Facebook. I draw an analogy to Intel. Moore’s law was great for them, because they could point at the world and say, “OK, in 18 months, someone’s going to fit this many transistors on a circuit board—we’d better be the ones to do it or else someone is gonna eat our lunch!” I look at this the same way. Three years from now, people are going to be sharing eight to 10 times as much stuff. We’d better be there, because if we’re not, some other service will be.
