I'd like to start by saying how much I respect tex exchange and all of its users. I am quite often amazed by the wizardry that some people have.
@Werner's comment above
However, I can see a discouraged feeling when ill-commented high-rep answers (like "Try this..." or "Here you go...") win discussion-filled and correct low-rep users.
completely sums up how I feel sometimes. As a fairly low-rep user, there have been a few instances when I have posted answers, only to have a high-rep-guru post a slightly tweaked variation that ends up outscoring my answer- sob! (I don't actually cry, don't worry.)
In such cases, it might be nice to make a comment saying something like, 'have you thought about using this...'. @Werner demonstrates this regularly- see the comment on @Mico's answer How to prevent page breaks in lists? ("Exam" class)How to prevent page breaks in lists? ("Exam" class) for example.
It does also seem that high-rep users are allowed to post one-line answers, and low-rep users are not. From the OP's perspective, a one-line answer is still a one-line answer, no matter who says it.
