For those of us who have had a formal art education critique is the right word. The problem is mainly cultural and a lack in knowledge of the conventions of figure drawing. This is an American owned site and most of the posters would be Americans with a smattering of posters from around the globe so American values would dominate.
We therefore have the issue of indirect communication verses direct communication. Americans are culturally indirect, I have been told they say three nice things before a negative comment, if they get to the negative comment, certainly they seem to prefer to say nice things or nothing. Saying nothing has the same weight as being ignored in a forum, in my opinion being ignored is the worst form of critique one can make to a post or poster. Without feedback its difficult to navigate one's way and so easy to get lost.
I've been told the Dutch are the most direct people in communicating, I know the French and Germans are direct while Asians tend to be indirect. I grew up in Australia where being straight was the chief cultural value if someone was straight with you even if you didn't like them you respected that. In today's politically correct and multicultural society in Australia I have no idea what our main cultural value is anymore. What it means is for me I tend to distrust indirect communication however the saying "when in Rome do as the Romans do" makes survival sense.
With the shift to modernism away from the conventions of the previous ideal/observation period in art add then the mess of post modernism it makes it difficult at times to know what is going on in a post. Finding out the intent and aims of the artist becomes important before any meaningful communication can begin. Not all of us share the same artistic conventions and values so we have to learn to get along, maybe, or not.
