memoir: yank out a pt. 4

Something feels wrong about the thought of mirroring a 50K word post
on Less Wrong. People would have to scroll down too far to read the
comments, and I want people to read the comments? Page load time on
that bloated JavaScript site? (Shouldn't be an issue; Jessica's
dramapost is slow to load, but that's almost certainly because of the
db JOINing all those comments, not because there's too much text.) For
whatever reason, a 35K word post feels better.

Not entirely sure about the title or the epigraph.
