More unoriginal unamusings:

the framework...I can see that the category elements were [aguably] designed to offer writers practical assistance in identifying those areas (if any -- ha!) in which a poem needs 'work'; but once a 'top-rated poetry' table is introduced, these 'labels' become largely irrelevant, reduced to numerical significance.
In most areas of life, a comment such as "That's clever" would probably elicit a reaction such as "Hey! Thanks. Do you want to count my scars?" (I won't go down the classic 'Would you like to suck my tits' route because, well, for some of us in the slight-of-stature sorority, that might not constitute a reward worthy of lip-licking, although it should not be regarded as sexist in any way. Recent Dept. of Health statistics indicate that the majority of males are equally capable of bestowing this form of positive reinforcement)
In the context of Poetry Ratings, 'Clever' infers that a piece is neither memorable nor well-written.
What about 'Needs Work'? In view of the amount of retrospective editing I perform on my stuff, I'd say that most, if not all of it needs work just to render it acceptable to me. And yeh, all of it could be improved, though some of it may be beyond redemption.
In the PR context, 'Needs Work' implies that the poem does not have potential.
So, perhaps these labels are euphemisms? Lifeless? Hmm, can't imagine it getting much worse than that.
'Original'? Wow! That must be something exceptional...but no, it doesn't even make the 'Imaginative' grade.
If the labels are not meaningful or of practical help, why not just have numbers? 1-5 is easy enough to understand and accurately reflects the nature of the rating system, where numbers are food for the formulae that determine the 'best' (and by implication, the 'worst') poetry on the site -- if that's what the Top Poetry pages are intended to display (or not).
Comments seem to be a more appropriate medium for meaningful expression regarding the specifics of readers' impressions. Some members here indicate, on their home/library pages, the extent to which they will welcome constructive criticism. I think it's time for emulation...
mabye we could have numerical icons adjacent to our names on posted poetry pages?
5: Bring it on.
4: Say what you feel, but I'll set the admins on you if you're really nasty.
3: Please be gentle.
2: Comment if you wish, but be aware my poetry is beyond criticism.
1: All compliments welcome.
