I've seen several of these now, here's an example: https://stackoverflow.com/questions/15045661/css3-transitions-work-in-ie.

The question has 3 duplicate votes, and yet, no banner is shown for it ("This question may already have an answer here:"). Why is that? What determines whether a question displays the banner or not? (Or has it been removed and I'm simply not up-to-date?)

we're now only showing the pre-closure banner "This question may already have an answer here" to the question owner. No one else, not even mods, will see it until after the question is closed.
                                                                                                                        --Jarrod Tiberius Dixon

Basically, there was some valid concern that it got in the way / encouraged pile-on votes / lacked a good, similarly-prominent venue for disagreement when displayed to all potential close-voters. So we're back to comments for everyone except the asker, who gets a big (hopefully helpful) banner informing him that his answer is in another castle.

If you look at that question now, you should see the banner.

  • Interestingly, even this can be confusing, this time for the OP, who doesn't realise that not everybody can see what has transpired to be an invalid dup-banner: stackoverflow.com/questions/15267676/… Commented Mar 11, 2013 at 16:30
  • Yeah, thought hey at least he responded. Nothing like getting a reply a day after you've closed a question wherein the OP finally explains why it's different...
