I saw when Facebook went from being yet another social network to being the social network. I remember then, them launching ‘apps’ on Facebook. I correctly guessed that the apps would lead to an explosion of not just the social network, but also activity (noise) on my timeline, and of intrusions of privacy.
If I had been ‘in’ the game then, I’d have doubled down on Facebook/apps and made money. I wasn’t in the game then, so I did the next best thing – I quit Facebook.
