Some of your issues are well taken and others imbue negativity while Nightstalker I see your point regarding other threads.
Personally I post what I believe to be a good, bad or indifferent image then thirst on the opinions of my peers in an egotistical desire to know whether what I've posted in worthy of being posted or do I need to go back to the drawing board and start again but that's me I'm an artist at heart.
