Each semester on the final exam in my editing course, I include an it's/its error for students to detect and repair. Most of them catch it.
Yet the confusion continues. This example is especially egregious because it's in the headline on the top story on a newspaper Web site. It's correct in the text, which makes this even a little more painful.
UPDATE: I checked back at the site about an hour after posting this and noticed that the bad headline has been repaired. It's unclear when that was done or how long the error was there.
