Well, recently I ran across another mention of this awful fanfic. On TV Tropes.
On a page for fanfic recommendations. Singled out as "one of the best Homestar Runner fanfics out there, and one of very few to mimic the character voices accurately."
I am not generally in the habit of using the acronym "WTF". In this case, however, I think it applies.
I mean, seriously. If this hideous trainwreck is one of the best Homestar Runner fanfics out there, I shudder to think what other Homestar Runner fanfics must be like. If this one actually stands out for getting the characters right more than other fanfics, I can only assume that other Homestar Runner fanfics involve Coach Z, distinguished Oxford professor of gender studies, moonlighting as a brilliant detective trying to put a stop to Strong Sad's murderous rampage.
As I said, I'd never been particularly interested in fanfics... but this is leading me to believe that the bar for what is considered a good fanfic may be even lower than I suspected. Drastically lower. Egad...
