Withersin recently made that issue available as a free PDF, so out of curiousity, I downloaded it. I've read the version of "Apt. #2W" that appeared in More Frightening Than Fiction, one of my free Nicky downloads from Lulu, and I wanted to see what an editor had done to it. When Nicky's "Observations of an Abandoned Seminary" appeared in Tales of the Talisman, the editor of TofT went over it pretty thoroughly and turned Nicky's dreck into passable, if still rambling and boring, prose.
The answer here is...nothing.
To my vast amusement, the following disclaimer appears in a box at the top of the first page of the story:
"The following autobiographical account has been left completely unedited in order to retain the author's original voice, intention, and mood. Withersin accepts no responsibility for the content."
In other words, the poor editor couldn't figure out how to salvage the writing so she didn't even try. I still wonder why she published it at all.
