It's a bit silly to think that the demographic of a community can change without the community changing. I have a policy of renaming particularly misleading or rabble-raising threads in the fora i mod once the initial post has been either resolved or debunked to make it more matter-of-fact. Like it or not, there are a lot more casual (or even drive-by) users posting in Talk now, and like it or not, they are more likely to take a possibly confusing or misleading thread title (or post) and run with it.
