Facebook capitalised by being in the right place at the right time, a time when the internet was opened to the non-tech savy, the "regular" world spilled into what was already a social experience. This is why Facebook now has the moniker of the "mom" platform. Technology like blockchain might free the business model from having to generate revenue and better align the experaince.

But I have an easier time believing people will just dump social media than some Utopian public social ledger is going to solve what is essentially a psychological shitfest.
