I applaud the decision of the SE designers to "gameify" their sites by introducing features like reputation and badges. For me that's a nice side-effect, but a brief perusal of my profile makes it clear that that's not the primary reason I participate on MSE, and there's the rub.
All too often, I find it mildly irritating that I can spend a fair amount of time and effort crafting a lapidary response to a question from a reputation-9 member only to get a comment like (exaggerating slightly here) "that was brilliant--you're my new math god" and no upvote or acceptance. In situations like this I'm reluctant to add a comment of my own about upvoting, since it seems too self-serving.
It seems to me that it wouldn't be too hard add a bit of code that would cause a popup to appear once only to first posts, indicating in a sentence or two the Stack Exchange etiquette of upvoting/accepting.
I understand that this might be appropriate in a wider forum, but I thought I'd first test the waters here.
