I think Kass is 100% correct. I personally have not seen a negative connotation attached to criticism except when it is unsolicited. Not everyone posting a picture on the Board is seeking “helpful” criticism. Maybe it is a first quilt and he or she is just proud to have completed it. No need to rain on their parade by pointing out flaws. If input is requested, by all means point out areas for improvement. Tips on how to improve are especially useful. Doing so by PM instead of publicly is tactful. Try to be kind rather than right.
