its not a bad idea if we're going to start tagging all popular yukkuri sayings. So far we only have flying in the sky but we can potentially tag all of it. But it won't be used much tht's for sure and like yuyukizen said... it's HEAVILY translator reliant.
I'd say to stay away from it just because its translator reliant, and seeing how little we use the its like flying in the sky tag i'd say it's probably a good idea.
