I learned that the hardest party to pull off successfully is Saturday night dinner. This meal is expected to be elaborate: appetizers, first course, dinner, dessert, and coffee. People arrive at 7:30 or 8 p.m. and stay for hours - definitely past my bedtime - and they all go home exhausted.
I think we will always have the impulse towards visual poetry with us, and I wouldn't agree with Bly that it's a bad thing. It depends on the ability of the individual poet to do it well, and to make a shape which is interesting enough to hold your attention.
