Concerning the posting of two or more answers separately, @Dan Bron asks:
Is there already an established or recommended best practice here?
This is what happened to me.
Once, when I was still a fledgling, I posted two answers to a question that boiled down to orthography. My first post was brief, to the point and effective but users asked me to "explain" why I sustained this opinion. Without wanting to clutter the first post, which had garnered a number of upvotes (3 or 4) I decided to post a second "answer", more detailed, containing more references, Ngrams etc. Effectively speaking it was as if I had written an extensive footnote. People were free to either approve or disagree, the response was positive and I received a higher number of upvotes than first post which laid pretty much dormant.
I was then asked (very politely) by a mod to either delete one of the posts or merge the two together. It was said that users believed I was looking to gain rep points unfairly, because both my posts could be upvoted. In short, I was accused of "milking the system".
Highly offended, I protested that several times I had seen users post two or more answers, and provided the links to prove it. It was pointed out to me that a user could post several answers if the answers were significantly different from one another. Only on those circumstances did the site permit this practice.
In the meantime, I remembered seeing one user who had posted six separate answers on one question. Again it was NOT a single-word-request, but a question dealing with grammar. The answerer had chosen to break down the question in six different parts, and received a total of (I think) eight upvotes.
When I signalled this discrepancy in the system, it was suggested that it was permissible because the answers were different from one another. I wanted to observe that however, all six answers could have been merged into one, but by this time it was clear I was losing the war.
In the end, my pride wounded, I chose to delete both my posts before the mod deleted one or edited my post to merge the two answers together.
After that episode I don't think I have ever posted two separate answers, but I have seen others do so, not often admittedly, and not only for single-word requests.
- If a user posts different answers which are distinct and offer alternative solutions, the site will tolerate this practice.
- If the separate posts can be merged, it will be encouraged but not necessarily enforced.
- If a user posts two (or more) answers which are linked to each other, and someone flags them, the mod is constrained to act.
