While it's worse when the author of the answer bugs the OP to accept their answer (for whatever reason - maybe they don't now there's a waiting period, maybe they don't know the asker knows how to accept, maybe they just want to fish for rep), I'm also finding many scenarios where other people are badgering users to accept someone's answer. This in spite of the fact that we long ago agreed to Let's stop displaying a user's accept rate for this exact kind of reason (well, more the nonsense about, "I will not answer your question until you improve your accept rate." - but this is equally obnoxious to me).
Today this happened on a very simple question where, after 11 minutes, a user badgered the OP to accept someone else's answer, and they did, even though the answer turned out to be wrong. The comments have been cleaned up so you'll only be able to see them if you're a moderator, in which case you'll need to check the revision history here.
Here is another example, where Martin's answer is clearly superior, but the OP was pressured into accepting the first answer as soon as he was allowed to (and before any problems with the answer could have been pointed out). This is why I don't like the 15-minute limit or the behavior of pressuring users into accepting answers. If they want to accept at 15 minutes, that's fine, but they shouldn't feel the need to do so. If they want to wait an hour or a week or a year before accepting an answer, they shouldn't feel pressure to do otherwise.
I've flagged many such comments as Not Constructive, and as far as I can tell most have been deemed helpful and deleted (but many of these were before we had any visibility into comment flags like we do today). So it is tough to come up with a lot of examples for regular users to see, because for most of the examples I've come across, the evidence is simply gone.
While I agree that in some cases brand new users aren't familiar with the site enough to know to accept, this is a very small minority of the cases I see. And I see no reason to encourage badgering for an accept when a question is 15 minutes old - why does the user have to accept an answer so early? Often better answers will come along later. I'm well aware of Jeff's reasons for the 15-minute limit, but I'm not convinced that it should be implemented the way he decided 3 years ago, and is worth revisiting.
So my reason for the post is two-fold, and is just aimed at generating some discussion:
Do you think we should revisit the 15-minute accept limit?
In lieu of that, should we be more strongly discouraging "early" badgering of a user to accept an answer as soon as it is technically possible for them to do so?
