As far as I understand most of the work was done on 8chan because the 4chan moderators banned discussions of the live stream from /pol/, but most users of the /hwndu/ board on 8chan originally came from 4chan's /pol/.

>it seems that most of the "talent", so to speak, has left 4chan amidst increasingly strict rules against various forms of tomfoolery.

I don't have any number to prove this but to me it seems that the overlap between 8 and 4chan is huge. There's very few 8chan users that absolutely never visit 4chan anymore. 8chan is tiny in comparison to 4chan so the signal-to-noise ratio may seem better there. (according to their front page they get roughly 2k posts/hour, if it was a 4chan board it would be medium-sized and 3 times slower than big boards like /b/, /v/ or /pol/)
