Ehh, I feel like this is written from the perspective of the investment industry, who foolishly pumped money into the incredibly-overvalued Facebook IPO.

No dismissive hand-waving can account for the fact that Facebook has little room to grow, and next to no goodwill among younger users. Anecdotally, I can say that by far the largest users of facebook on my feed are 50-somethings posting the sort of libertarian pseudo-intellectual shit I used to get forwarded to me in emails by my grandparents.

Kids might not be reliable tech predictors but if they aren't adopting your product with no room to grow outside the Kid Demographic, then good luck to you.
