I don't have a ton of time to spend in the community lately--stupid real life, I hate you--but whenever someone asks for feedback on a story, I at least read it and try to come up with something specific and constructive to say. I have offered generic and unsolicited advice to writers in the past because of my career and experience, but that's not as good as "I wrote this" followed by me saying "Okay, here's what I think about that specific thing you wrote."
Years of being on deadline have taught me one thing about copy: If it's broke, fix it. Lose the ego, lose the hurt feelings--if you've come to me and said "Here's work I've done, tell me what you think," I will tell you. You will get feedback. You may not like it. Apparently, some people are even shocked by it. Welcome to the world of Other People's Perspectives. Welcome to the world, period.
Short version: Do not ask for feedback on your work if all you really want is a compliment. I give those too, sometimes at the same time as the criticism. But don't take me or anyone else with relevant experience to task for actually trying to improve your output. Don't blame me for giving you exactly what you asked for.
