I have little sympathy for TFAuthor failing to spam their slop on Reddit, but I will say that Reddit pretty definitively replicated the key findings and observations of Usenet’s eternal September: online communities don’t scale.
I’d wager that there was a time when a supermajority of Anglosphere internet users were on Reddit. I could see why that’s enticing for the advertising douchebags that run Reddit, or perhaps for stroking Steve’s planet-sized ego.
But we’ve seen at least twice now that large online communities are not workable without becoming user-hostile. We need to reduce federation and centralization, and normalize smaller online communities again.
