I suppose the reason I don't criticize is I "accentuate the positive", trying to encourage people to keep at it. I have weak and strong areas, and am acutely aware of the former. OOH, if someone asks for critical feedback for improvement in a certain area, that is different. However, I think the biggest deterrent to posting music by most ,is being shot down, whereas applauding(sincerely) the strong points encourages further participation. Telling it like it is, according to their own opinion, should be used very judiciously.
