Suggested meanings of the ranks:

0 – Has no sense of poetry
2 – Naïve and badly written
4 – Naïve, even if well written
6 – Promising, but flawed
8 – Good, has depth and meaning
10 – One of the 20 best poems I’ve read in the last three months

Problem -- what about really well-written poems that purposefully have neither depth nor meaning? Silly poems, in a word.

I rarely defend this point of view, but depth and meaning can be overrated sometimes. Look at the dear old Reverend Dodgson. I care not what the Freudians say, his things mean nothing, are not deep, and are absolutely brillig.
