Pardon if this has been discussed before or brought up since I can't seem to find anything on it, but I was wondering about this tag. I've read the wiki and understand what its intention is, but isn't that somewhat of a subjective subject and thus more Pool material than tag material?
For instance, one of the posts with that tag was said to have been tagged for Cirno because it looked somewhat like her arms behind her back are forming a 9. And it somewhat looks like a 9, but not strikingly so and just as much looks like just her holding her arms behind her back. Though the arm reasoning was conjecture.
That's the other thing I want to ask about the when_you_see_it tag; how does one confirm the tag or not? Almost none of the posts with the tag have comments from the uploaders/taggers as to why it was given the tag or not. So when I look at an image with the tag and see nothing shocking/off/odd/startling about it, I just need to assume that whoever added the tag put it on the image for a reason, since I can't disprove that there's something hidden.
Really though, I get the idea and I do like it. I just think it would be better as a pool really. And pool or not it would be really nice if people who put the tag on an image would post a comment (with spoiler bar) with what there is to see that makes the tag/pool inclusion appropriate.
