I like the video, but I'm a little bothered that she misattributes su3su2u1's critique to Dan Luu, who makes it very clear he did not write it:
These are archived from the now defunct su3su2u1 tumblr. Since there was some controversy over su3su2u1's identity, I'll note that I am not su3su2u1 and that hosting this material is neither an endorsement nor a sign of agreement.
I can see why these would appeal to LW crowd. One of them writes cosmic horror about monstrous alien phenomena that can't be directly perceived preying on humanity and all life in the universe, and qntm writes wordy science fiction.
No comment on Wildbow. I'm sure Worm is excellent but I'm just not in the market for three HPMoR wordcounts of capeshit, so I don't know what his deal is. Bummer for him to have one of his characters be the indirect namesake of a notorious murder cult.
