It's not what you say, it's how you say it. There seem to be those who think that any sort of criticism in gallery posts should be forbidden. To prpperly address this, you have to understand two things- the purpose of gallery images, and the nature of criticism. IMHO, the entire site is dedicated to artists who, regardless of their educational level, are trying to improve in some way. One of the available elements for this is feedback from one's peers. Cirticism can be a powerful tool for improvement if used properly. What we have is a moderated system. Constructive criticism- along the lines of "for improvement, it might be better with x, x, and x"- is welcome. Unnessecary criticism of the artist or image- "this s*x, you stink"- can be deleted by the moderators. In the absence of a perfect system where everyone understands the value of constructuve criticism, this is the best we can do. Value the good ones, ignore the bad (and report the really bad). I would not, however, let a few bad eggs ruin the whole benefit for everyone.
