- Someone at TMW, probably on their Matlab Central team, would post a blog entry, once a week. This would entail them reading through many Answers posts every week. Yes, they could invite e-mails nominating solutions to highlight. But it would take some effort.
- Use this very question. Every week, or whenever you feel moved by an excellent answer, post an answer to this question, that highlights that answer (with a link). Add enough context about the question and what you feel to be the best features about the answer.
What answers should be "Answer of the week"?

In MATLAB Answers, many answers are good enough to satisfy the questioner; but some go further. They may take extra care in explaining some MATLAB technicality or the reason their solution works. Or they may go beyond the question that was asked to address a broader issue. Such answers are all the more remarkable because the contributor knows they are in a race: someone else may post an adequate answer and have it accepted before they are finished.
That came home to me when I saw this answer by John D'Errico to the question find all answers to the equation. The problem was how to find the roots of exp(-0.2*x)=(x-2)*(x-3)*x. The accepted answer was pretty good, using a sensible approach to find three real roots. But D'Errico went beyond that, posing the question "How will you KNOW that you have found all solutions?" and demonstrating a root deflation method that returned several complex roots in addition to the three real ones. But how many people are ever likely to see this answer?
The File Exchange has the Pick of the Week blog to highlight especially good contributions, but MATLAB Answers doesn't have anything equivalent. That is why I have created this question. What answers do you think deserve highlighting? The answer can be from as far back as you like, and you don't have to wait a week after the previous post. Just share it with us so other people can benefit from it!

This seems like a nice idea. It might encourage people to spend just a bit more time writing an answer. That can never hurt, and it can only help the person who needs the answer to their own question.
I see two viable solutions.
I vote for option 2. It is trivial to implement, whereas option 1 would require someone from TMW to be willing to dedicate their time and energy. And since anyone can add an answer, you effectively have hundreds of eyes available for the search, so no single person needs to invest a large amount of time.

What criteria do you want to use? Brilliant but verbose essays that appeal only to the Editors and other cognoscenti? Short, succinct responses that reduce a complicated Question to a simple (and in retrospect, obvious) Answer? A mathematical ‘proof’ or derivation that educates the ‘Querent’ in the broader implications of the Question? A condescending (albeit correct) explanation?
Other than a direct answer to a homework question (to be eschewed if at all possible because it’s rather blatantly cheating), would not the ²best’ answer be the one that educates the Querent to the greatest degree and has the greatest value to other potential Querents?
I, honestly, have no firm idea. I would propose that ‘Best’ Answer or the ‘Answer of the Week’ be the Answer that most likely stands the test of time (absent MATLAB ‘upgrades’ and ‘improvements’ that might make them obsolete in a future release) but that educate in the broader sense the underlying mathematics involved in mathematical programming, and specifically, of course, MATLAB programming.
It is easy to answer a specific question, but does that answer do anything more? If not, it is not a candidate. Is the answer one that stimulates the Querent to do other research on his or her own? If so, that may be the winner. That my criteria are the primarily ‘pragmatic’ or secondarily ‘utilitarian’ approaches is not coincidental. They are my weltanschauung.
So what is the ‘Answer of the Week’? In my pragmatic view, the Answer that stimulates the most subsequent exploration and understanding by the Querent and all who read the Question and Answer. We can, as the AAMPAS does, pat ourselves on the back and tell us how wonderful we are. But I would like to leave that decision to the Querents and other end-users to determine. This not only puts the Querents first, but tells us what they want to know, and how they want to know it. (I realise that this includes those who need to produce a Nobel-quality paper by tomorrow morning, but it also includes brilliant people who quite literally ‘never thought of that approach’ and learned something — possibly very valuable — from it.
