drac, I agree in great part with your assessment on the commenting in R'osity's galleries.  It took me a few years to feel brave enough to post anything here because I was terrified of receiving criticism.  So I began posting elsewhere even though I was a member here first. 

Later, I began craving criticism. I'd reached a point where I felt it would help me improve.  That's when I finally took a deep breath and began a gallery at RO.  Lo and behold, I was surprised to see how the commenting had changed.  Gone seemed to be the critiques and helpful suggestions for improvement in lieu of gushing, overdone comments. Don't get me wrong - some images here are truly excellent and deserve the accolades they receive.  But IMVHO, definitely not all.

If done properly, constructive feedback can be a wealth of info or help, especially since the commentor is not married to the image & able to provide an impartial perspective.  Whenever I have received constructive crits, I've usually sitemailed that person thanking them for taking the time to do so.  If it will help me improve, I am appreciative that someone felt their time warranted helping me by their suggestions.

I would like to see the spirit of helpful crits return to R'osity.  But with so many here who get bent out of shape if everything isn't "OMG that is just amazing - Huggerz!!!111!!!", I doubt we will ever see this approach return 100%.  IMO, that is kind of sad.

I dare you, while there is still time, to have a magnificent obsession. --William Danforth
