If I could mention, in defense of Basement Bettas (whom I don't actually know in real life and haven't dealt with, I might mention), she is a professional betta judge. I edit novels for a living, so I am well accustomed to needing to tiptoe around feelings while giving people an honest opinion. When you do something professionally, you become accustomed, though, to looking at particular points, and if you are normally allowed only a small amount of text in which to evaluate something, you do become terse; it's simply part-and-parcel of the job. The people who are best at this type of work generally do work hard to find at least one thing to compliment, as well, simply so as not to discourage participants. I haven't followed enough of Basement Bettas replies to know whether she does such a thing, but the work is being accomplished even if she doesn't.
