Interpretation...is it valid critique?

[milo]

If your writing is so obtuse or complex that the success of the poem hinges on people interpreting it, you should probably consider rewriting it for clarity, I would think before posting.

I should add that poetry isn't about what you said, that really is better accomplished through prose, it is all about how you said it. If you think your meaning is so important that you litter up verse with poor technique and think it is still good you are wrong. Poets are wordsmiths. They create enjoyable art with words.
