Instead they focused on growing the network and making content creation and broadcast of content free.
So today less than .5% of content produced is consumed according to the UN report on the attention economy.
Whats the fix? Content production needs to be scaled down. A better system is required that decides Who gets to broadcast, how much and when.

"Scaling things up" should be a political/social decision not a business/technical decision.
The focus must be brought back to solving info overload.
