That video is really, really awesome! And it won't leave you feeling "Japanese" either. (Which is a great people, btw. I'd really like to go there someday, mostly for the food and language and history. And Anime also, I'm forced to admit.)
That's too harsh, and not in the spirit of the site. Right from the beginning, pg made this distinction:
Empty comments can be ok if they're positive. There's nothing wrong with submitting a comment saying just "Thanks." What we especially discourage are comments that are empty and negative—comments that are mere name-calling.
I'm pretty sure I've seen dang or pg say that quick, low-effort comments that express enthusiasm for a comment or post are fine (whereas low-effort, drive-by dismissals are very much not fine). I've tried searching but it's not obvious what search terms would turn up such a comment.
But I hope my recollection about that is right. Yes we want comments to be substantive in general, but we don't want to be surly or even Grinch-like when someone is just expressing excitement and affirmation for someone else's contribution. I'm sure that's not what pg or dang would want here.
