Yep. There are two separate problems: original titles created with an overly-high amount of concern for people clicking through (linkbait) and original titles created with an overly-low amount of concern for people clicking through (interesting personal blog posts titled "some stuff", for example). Both of these should be changed to solid, standard news titles that inform the potential reader about the content. Letting people change titles eliminates both of these problems, at the occasional expense of a crappy title being submitted and promptly flagged down. Graham's solution is worse than the problem it purports to solve.
