(Preface, this is not mainly about the question in question (sic) - or it's editor, but the general handling of such changes. The question change initiating this just a great example for the issue and how it may effect our workings)
I just stumpled across the change of a questions title that not only canged its meaning in fundamental ways, but also made it quite snugly fit a previous writen answer. The questions original title did read
What limited the use of the Z8000 in personal computers?
clearly asking about Z8000 and personal computers. It got changed into
What limited the use of the Z8000 (vs. 68K and 8086) CPU for 16-bit computers?
Now changing the very core of the question from personal computers to generic comuting confined to 16 bits and introducing arbitary other CPUs as direct referens of wich only one (68k) as mentioned in the question, while the other never was.
I do considere the change substantial in context of what the question is asking.
Changes that drastic can invalidate and marginalize answers that did (as they should) focus on what has benn originally asked.
The fact that he change was made by the author of an otherwise well formed, reasonable and informative answer did trigger my assumptuon that here soem retroactive editing happened. No doubt, this may well be unintential by the editor, as it reflects his own interpretation/wordign of what is asked. Still, it's way more than just a clarification in wording. Isn't it?
I feel it's very important that answers should stay true to what has been asked, so changing questions is a very delicate matter to be handled with extreme caution.
So, how to handle this?
(And no in advance, an answers autor not objecting a change isnt the same as aproval.)
