An overabundance of typos

I've been seeing them everywhere. In one of the books I'm reading (Clive Barker's Books of Blood), in my neighborhood's weekly paper, and in restaurant menus. In TV commercials and on business web sites. They taunt me with their wrongness. I can overlook a typo or three in a blog or an email--heck, I've been known to commit those venial sins myself from time to time. But blatant spelling and grammar errors in a book that's in its third printing? Even spell check, imperfect as it may be, would catch some of the worst errors. What happened to the editorial process? Do people just not care anymore?
