So Facebook totally messed it up. What would be the correct system. Why hasn’t anybody built it, or if they have why has it not made progress into killing off Facebook? Is the problem that ultimately people can’t handle social media? That position seems extreme but I wouldn’t be the first to suggest it.
Or is this like credit cards, where the majority of the population manage them just fine, but a nontrivial percent of the people are just not capable of being responsible and make a huge mess that gets blamed on society at large?
