The eXploz Hack is awesome!!! I just installed it, and it does everything that I've been looking for in a URL Hack. Not only does it do a fantastic job of headline information to the title tags, but it also puts the headlines in the URL, and creates real names for the Topic IDs. It does all of this without breaking and invalidating current and old URL paths! This is a hack that should definitely be part of the new core.
