as with everything, depends on the critique, but ALL critique/comments have value since they let me see how my writing's being perceived through eyes (and minds) other than my own. it allows me to take a step sideways and view it from an alternate perspective, see what's muddy and needing clarification/scrapping.
how much i'll edit a piece because of what's been said will vary on:
a} my own respect for the writing of a critter
b} my own emotional detachment from a piece
c} how many people concur with the suggestion - if 3 good poets tell me something i'm doing isn't working? i'll definitely listen
d} if it feels right to me, for my poem's own voice - you can't please everyone all of the time, and shouldn't edit with that attempt in mind!
a critter who tells you what to change in your poem using how they would write it, paying no attention to the poem's voice? that's a non-starter. the best critters suggest changes using the poem's voice, and some can give great links to writing studies that can blow your mind! the improvements have to come from the poet - a critter can only steer in certain directions and if the poem-horse wishes to run there.
for me, the best piece of crit i ever received was from a poet i really trusted and admired; i used to write really realllllllllly long pieces, back in the day when words were white-water spills. he told me ''you know i love your writing, but that longer stuff? kinda gives me the shits'', lol. brutal. but because i respected his eye and ear, it made the hugest change in my writing: i was mortified but it spurred me to take hold of the word-reins and begin controlling my poetry instead of allowing words to control me. i pared back to strictly minimalistic writes, then was able to relax more and expand a little. it was the best writing exercise i could have ever had.
every reader will interact with your poem in a unique fashion - they bring their own life experiences and preferences with them. if i chose to write a piece about - let's just say the wonders of brussel sprouts! - those people who loathe sprouts are never gonna like it.
