Over on http://english.stackexchange.com, I created a question that contained unintentionally polarizing subjectivity. Because of this, I am now faced with the possibility of siding with a single answer instead of my desired goal: to promote both answers equally, because both contain useful, topic-relevant, pithy information that answers the question completely.
I would prefer not to leave the question without an accepted answer for reasons obvious to those familiar with the reputation and sorting systems here on StackExchange. But at the same time, I feel leery about creating my own answer pointing to theirs and selecting it as accepted, as this may siphon reputation away from the authors I wish to promote and earn me badges that are inappropriate to the situation.
Before I continue, I note that candidate solutions to this scenario are discussed here: Why Isn't There a Way to Consolidate Answers?
However, I feel that this linked question is incomplete and that following up on my candidate solution is necessary, for an excellent point raised by Mike Grace in his answer:
I have been contemplating this same thing recently. I plan on accepting the answer that most completely or clearly answers the question but also inserting at the end of my question a section where I outline all of the parts of the answers that I found most helpful with each users name. I disagree that the person that asks the question should compile all of the answers together into their own and then choose their own. If everyone started doing that, the motivation to answer question well and completely would be partially lost.
In which I agree and note that his solution is inapplicable when two or more authors provide the same degree of information content, such that selecting one over the other as accepted implies favoritism when none is being deliberately expressed.
So, I return to my original question: is creating a summary answer and accepting it, as OP, considered bad practice? It seems like the most correct thing to do in this scenario, despite the flaws discussed above.
(Note this is not a question asking for the possibility of supporting multiple accepted answers or splitting bounty reputation amongst multiple parties responsible for pieces of the solution, as discussed here and here. This is purely a question about best practices borne from the existing tools currently available for a limited portion of the problem space.)
