In my opinion, most new users who post their first question generally fall into one of two categories:
People who post the question, get an answer they like, then ignore the site whatsoever. This is obviously counter-productive to the community, but there's not really much we can do.
People who care about the site's rules, post the question, follow answers and comments, participate in the discussion, upvote, etc.
The problem I see is that most newcomers of the second category accept an answer to their question within minutes of seeing the first one (just my observation). And on a site that hosts questions that are more subjective than these on SO, this is a bad thing (again, IMO). Honestly, I'd say even on SO this is a bad thing, but this is off topic. Many people don't bother answering questions with an accepted answer. And even if they do, the OP is less likely to change the accepted answer. And even if he did, this has stopped some potentially good answers from materializing at all. Furthermore, the answer/question ratio is used as a metric for new SE sites (and a healthy value from what I understand is about 5-6).
So, shouldn't there be something in the FAQ that mentions to new users they should not mark the first posted answer as accepted, just because it makes sense?
I mean, great answers take time to be written. On my questions, I wait until either the question seems to have little new views, no new answers and few comments, or I've seen an answer that covers the question in its entirety flawlessly.
Is this a real issue, or is it just me?
