I have noted a sharp increase in spelling errors in news reports recently. That's to be expected in the blogosphere where there are no editors. But here's an example from the Miami Herald's on-line edition: (writing of Obama's drop in the polls)
"This will require him to find ways to either win back the middle or energize his base in ways that hasn't happened so farm" Miringoff said
I would have thought that any editor would have caught this.
