MichaelFeathers redirecting BradAppleton's comments from XpFreeZone:
Might it not be advisable to throw in a few words with the new page reference to explicitly clue someone in that something was moved, or (if it was deleted entirely) removed? Leaving no indication of what's happened seems likely to offend IMHO, making the person feel they're being treated like one of Pavlov's dogs instead of as a person deserving the courtesy of an acknowledgement. --BDA
Definitely advisable to throw in a few words. Not doing so would be discourteous. It might also be ineffective as someone might presume that the remove/moved part had been accidentally stepped on.
If the discussion was diverted off a path someone wanted to pursue, either branch (maybe even both) might be moved to a new page. I think which depends a lot on the context and what makes the best natural fit. (Whatever that means. Various issues have previously been raised in other discussions about renaming and otherwise refactoring Wiki pages.) Whichever is chosen, the "pointer" left behind should be stated in a positive manner, focusing more on the desired direction the discussion should follow on the page than on what is off limits. --KielHodges
Good way to deal with ConversationalChaff and allows continuation of the interests of the originator and the diverter.
