The first social media revolution started ~20 years ago.
The features may have changed, but the general structure has remained intact since then.
Since Friendster, every social network's value has been contingent upon grabbing as much of a mass of people as possible, and leveraging the network effect.
Why was MySpace, Twitter, Facebook valuable? Because of how many active users were on it.
At least, that was how the first social media model worked.
When Facebook and Twitter were pitched to VCs, a key value proposition was that these corporations owned the network effect.
Owning the network effect, meant owning personal data of every person who used the social network -- and then leveraging that data into other revenue streams.
For awhile it worked.
We were happy to give up our privacy and personal data in exchange for access to social media.
