Some title changes are bad, but I do remember one title change that was partially good. Someone posted a link to the site http://lobste.rs/ http://lobste.rs/ with a title like "Yehuda Katz creates new Hacker News competitor". But that was factually false - Katz was merely an early user, and was not involved in creating or running Lobsters. The story got what you could consider an unfair amount of attention, since I bet many people clicked on it just because of Katz's name. The mods eventually changed the title to "Lobsters". That failed to convey the relevant information that the site is like HN, but at least it removed the false information about the creator.
