Consider this: What makes a good node title?
My take on this is that the title is part of the content, and shouldn't be tampered with, both for the benefit of the poster and the benefit of readers. For instance, a node titled "How do I reggex PERL" tells you a lot about the poster. However, adding additional words for searching purposes (or adding correctly spelled ones) can add a lot of value. So I'd like to see title changes just add additional info at the end, perhaps in () or . Just my 2¢.
