Yeah, if you ever want a detour into true madness, try to find some of Ditko's prose on the internet or in Douglas Wolk's book Reading Comics.
I used to be charmed by insane SF/comics writers, but then last month I tried rereading Robert A. Heinlein's Number of the Beast. Terrible, terrible mistake.
Re. Apocalypse Nerd: it was good, but I found it totally depressing.
