I'd go one step further, and blame our growth obsessed startup culture. So many incentives to get people to share so a product can go "viral". Strava has a number of anti-patterns that make it difficult to do what you want with the app, rather than what they want you to do. (Share! Tell your friends! Brag about how fast you just ran this! Compare yourself to others!) I think this news-event and some of the struggles Facebook has are highly similar (they're experiencing the pullback after years of inducing users to help them game their numbers).
