So, my understanding is that, unlike SO, the accepted answer is usually the one the user finds most useful, rather than correct (questions obviously being subjective).
Given this it seems odd that people accept answers so quickly - often within minutes of the first answer being posted.
Should there be some threshold which has to be passed before an answer can be accepted? After all, while the questioner's opinion of the right answer is important, accepting an answer discourages further answering and limits the sharing of experience on the subject.
Edit: In light of Jeff's response that there is already a 15 minute limit. Shouldn't the limit be slightly higher - a few hours, maybe a single day (to allow all timezones to comment?) - given the more subject / sharing nature of questions here?
