The Blog Formerly Known as TheDailyWTF is a favorite of mine, although not for the snippets of horrifying code. What they do surprisingly well is expose the human factors behind bad software. Thus far, the “Virtudyne Saga” is probably the best article of this sort, but someone with a little experience and a perverse sense of humor can usually figure out what sort of horrible environments produced the ghastly code that gets pilloried there.
My main worry is that TBFKATDWTF encourages the crowd who can’t read code but insist not only on writing code, but imposing their limited understanding of the subject matter on others.
