for social media though that's a pretty important end goal. If the people I want to follow aren't using it, then I don't want to use it either. It's like with messenger apps - the one that everyone else is using is the one that wins. And if they aren't using it and I am, then part of my use of the platform becomes trying to get the people I want to talk to onto the platform. It's not a silicon valley thing - it's a communications thing. "everyone is using it all the time" was an important end goal for the post office too, and highways and other shared infrastructure with network effects.
