The nature and structure of WWE programming intentionally encourages constant discussion like this: it's random, frustrating, constant and accessible. The talking points remain the same, making posting a rote, reactionary and reflexive task.
The endless feed of content means these talking points are constantly refreshed (I'm sure you don't need me to list them). Most people have a personal history with the company, mostly rooted in the AE so there is always a connection, a spark to say something about the product.
Then when they do something right, it energizes the average hatewatcher enough to knuckle down and continue watching for another however many months. Sometimes the gap between those moments is too long and they drop off.
This isn't possible with other feds - the only company that runs half as regularly with anything approaching the same production standard of WWE is Japanese, which is a massive style and language barrier. There is no effective competition, meaning WWE will always dominate discussion then, now and forever.
