It seems the the rise of influencer culture led to everyone else feeling like they had to only be in a specific niche, and only speak about it or they weren’t going to serve their “fanbase”.
And you know they’re probably right that they wouldn’t serve that fanbase, but good grief has it made the net a generally much more boring place with space only for near-deified experts & influencers and perpetual newbs, leaving little room for anyone in the middle to have nuanced and varied conversations.
