After the end of the startup era
I look at it from another end - I feel there is a sort of an app fatigue. Maybe it is jut me. I used to be excited about Uber-like things, note taking apps, DropBox, coupon sites, review sites. Installed some of them, used them, then kind of stopped. Someone at work would say "you should try this new thing, totally cool" and I'd be inclined to do it, but now would pass it probably.Extrapolating scientifically from the sample of 1, it would seem that a small loss of excitement over trying new services and apps over the larger population would be enough to prevent the fabled hockey stick growth. No hockey sticks -> no unicorns -> less VC money for new startup -> articles about the death of startups -> comments on HN about articles about the death of startups
