An Internet product is very often a thing that lets other people make things — a kind of metaproduct — and you can get 30 million people working for you, for free, if you do a good job of it. Facebook, for example, is dozens of these products at once — chat, walls, feeds, calendars, and so forth. Thousands of people work on building these products — including plenty of product managers […] From a certain angle, Facebook runs the risk of becoming like Apple before Steve Jobs returned — too many products, each with teams sworn to defend them.
