There's definitely an old internet culture that eschews social media and it has seemed to grow (again) over the years. One example is Freenode:
- The network has some moderation, but bans are last resorts where on social media bans and temporary bans are part of the process.
- Much of the moderation is left to channel operators and guides are given by the network on how to moderate.
- Much of the network is apolitical and you can even be banned for talking about politics in many channels. This runs counter to pop-culture with encourages not only discussing politics but airing your politics with known dissidents.
- Nearly every channel is topic focused, where pop-culture and social media encourage broad, boundaryless discussion.
- Pseudoanonymity is still an option; in contrast to real identity policies in social media.
You can't tell me that's not culture, but maybe it's not a whole culture just yet. That said, keep poking the bear cub and see if it doesn't grow up.
