We now have a new form, circle--modernism. It's been bad enough that we've had to suffer a generation of dull poets writing poems about poetry (PAP) where the subject seems to be either the poet as sensitive being channeling the variety of vibes that the rest of us cannot discern, or the inability of poetry to "get" at the exactness of the moment. Now we have writing in praise of writing about poetry.
There is a good amount of log rolling here, with more than a clutch of poets intent on not giving away the game on which careers and reputations are built on, but one does admire the adroit skill that gets applied to the least interesting of the least tangible poems. What is even more interesting is that a good amount of the essays exclaiming the value of these poets under nominal review don't actually explain how the poets are successful at their tasks; more often we get an examination as to the poet's intention, and then a long run in eloquence describing results that I , for one, rarely witness.
I ought not generalize too much poets remarking on the work of other poets, since there is a difference between actual criticism-- evaluation based on close inspection--and the sort of careerist suck-upping one finds on the back of new books. There is the idea that some wag had put forwarded about poets who put forth their own theories about they and their associates do; the theory is more interesting than the poetry it discusses. It is, often enough, more poetic.
