The wire service knew in advance that I had never shot a hockey game (I warned them up front) and they asked me to do it anyway since everyone has a first game of shooting every sport. I share all my experiences shooting on my blog, even the bad ones, as a learning tool, and you can see from the comments it was appreciated.
My question to you is: why would you spend your time on forums criticizing other photographers? Does it make you feel better about your own photography?
Oh yeah, by the way, I spend my time on forums giving advice because that's how I learned. I don't think I've ever criticized others work without giving a reason behind it. (If I have then accept my apologies).
There's no reason to tell people their photos look good if they don't. It does them no good.
