It's more interesting now for a couple of reasons. The board was raided by "social justice warriors" during GamerGate and many stayed to keep arguing. Another reason is 4chan/pol/ is tamer that it used to be. The worst kind of uninteresting stuff moved to 8chan after GamerGate.
I suspect some also go siphoned off when the larp that was Q migrated from 4chan to 8chan.
