Pop culture spreads using the instruments of media (social or conventional). Presence of ubiquitious media in the age of the Internet and snatching everyone's attention - now we have a recipe for a total mob thinking. A giant hive of people (often passionate and angry) moving in unison for a singular ideology. We've created many of these mobs. Intellectual people are also losing their grip on truth.
Before the internet, there was some damping factor in how information was distributed. This allowed for time and place for debate. How do we balance this? We desperately need instruments of truth without care for what the majority/minority believes, thinks, accepts, rejects or promotes.
100 years from now we're going to look back at this chaotic time in human history when we didn't know what to do with the Internet.
For nature doesn't care about anything but the truth.
