Instagram didn’t create a problem. They didn’t introduce the idea of photo sharing, they just simplified the process. They solved a problem other people hadn’t recognised, and they didn’t make anything worse while solving it. They didn’t make anyone’s life more complex. They added a lot of richness to peoples’ lives who now have a community they didn’t have before.

That’s where you get something successful. I think there’s too much focus on, ‹if you think of a problem, then there must be a problem,› as opposed to making sure that what you’re identifying as a problem is actually a real one in the first place.
