I don't think that people who consider the planet "sugarly," or who dislike short positive comments, differ with the substance of the posts. I think the "issue" is that while repetitive, short-on-content posts can be easy to write, they are boring to read.
In my view there is some truth to that critique. I would rather read posts that explain why someone liked something or even minor critiques than the same old one liner "greats" and "excellents" repeated over and over again. On the rare occasions I post a figure, I would also prefer to know what specifically somone likes than a generic well done. I recognize that that's only my opinon and that others my well disagree.
I don't think that means I have too much time on my hands but it does influence how often I go into the forums to read posts these days.
