When reading answers I often find myself in the situation, that all my thoughts are already taken up in various questions, but never incorporated into one answer. Frequently the answers are of this kind:
In addition to @Xs answers, I want to add that ...
In my opinion, this is cumbersome for somebody visiting the site and looking for an answer. Thus I would write an answer containing aspects from different other answers, obviously attributing to the original answers. But my answer will only contribute minor differences from the originals and will essentially be a summary. As mentioned in the following question on meta.SE this might be offensive, as I might steal upvotes:
So in short my question is:
Are summarizations of answers (with just minor changes) good practice or unwanted duplication?
From the question linked above and the reactions here so far, it is clear that summaries are not wanted, rather editing existing answers (writing a new and better answer is of course the best, but not what I aim at in this question). So as an example:
https://outdoors.stackexchange.com/a/8104/3602 The inputs in this answers are in my opinion absolutely relevant, but the reader has to search for the referenced answer and read it, to fully understand it. A full quote of the referenced answer by Michael Borgwandt would solve that, but its cumbersome.
What is the "good" way of writing such an answer that is based on another answer?
