You see, I think people follow that principle until something sticks in their craw. I'll use myself for an example: I've had good reviews, not so good reviews, and some bad reviews. And, by these, I'm not referring to how the reader liked the stories; instead, I judge this by how well the reviewer did in pointing out things they didn't like about it or maybe canon boo boos that I hadn't thought of. A story could receive ten squee-filled reviews or even a SPEW review full of praise and adoration, but getting one with poorly put concrit can ruin all of that. To this day, for a fic of mine I particularly love, I have one review out of 15 or so that makes me look back at that story and not think it's half as good as I thought it was when I submitted it. I don't even know if I like the story anymore, which is strange, since I'm not what you'd call a delicate flower. It just rankles. And to your point, it's really hard to focus on niceness when one isn't feeling particularly friendly with the reviewer.

Not having to worry about that makes reviewing a lot more fun.
Oh, and still super stoked for the triplets!
