for me personally, I'm not writing to write better, or asking for critique...I feel personally, some people like vanilla, some like choc and some really enjoy strawberry, so, it always amazes me, how people can critique books, movies, poems, etc....so many times in the past, I've stayed away from movies, due to reviews...later to rent them and couldn't help think, "What could they have been thinking".
For me personally, my poems are many things, including really not caring if anyone else likes them or not, you see, they are for me a growth process, they give me the ability to open up & speak out honestly, without getting hammered or attacked for my beliefs, my poems have helped me change, just by the verification of my feelings on paper, they are for me, who I am, my identity, a hype or perhaps better said, a way of talking to myself....
some have told me, my poetry is long, and I know it, they say, less is better, and I know that as well, but it's my voice, who I am...and to critique me I feel, would be hurtful after coming so far, through poetry...yanno?
What I'm trying to explain is this, unless your in the forums that strickly ask for honest critique, if you do so on a constant basis, you might scare someone away, who is just coming out and starting to bud?
Some poets, and I speak only for myself, are very sensitive, besides, I believe there is some very inspiring, talented poets in this site and find, it's just nice to sit down, kick off my shoes and stay awhile, listening and learning from them
and so, I hope my comment has offered some enlightenment on your question...about critiques or comments...it is not written in stone, and I'm certain, not everyone feels like I feel on this topic.
