We're a long way from having any semblance of a complete art of rationality, and I think that holding on to even the names used in the greater less wrong community is a mistake. Good names for concepts are important, and while it may be confusing in the short term while we're still developing the art, we are able to do better if we don't tie ourselves to the past. Put the old names at the end of the entry, or under a history heading, but pushing the innovation of jargon forward is valuable.
