I would be delighted to see a return to quality limericks in which the following maxim were applied by all: "If you can't think of a line that scans, rhymes and fits the context, let someone else write that line." The Limerick is the only form of poetry I really enjoy, so I'm delighted that some effort is going into restoring their former greatness.
I am pleased by the mandatory preview. When I first came across 5 (although I still feel like a neophyte), the limericks being posted were on average outstanding. Being pedantic is no fun, but the general high standards made me try harder.
Hmm.. Not sure about mandatory preview on chat games, or things like AVMA. But cheddars is certainly one that could benefit, as could poetry games more generally. What do people think?
