The word processor is the villain in much of this.
One horribly common horror that i absolutely loathe by the way, words that are supposed to be SINGLE words, and both people and especially spellcheckers and crap, cut them into two.
Like the fic i was just reading, graveyard spelled as grave yard. Hallway as hall way. Backup as back up(*cringe*). And so on...
It's a total plague, coming over the last 20 years.
