I won a general understanding of poetry. I had thought it was obsolete once writing became common. It is easier to remember than prose, and has error-checking built in, but it makes it far harder to find words that express a given thought. The chance associations of rhyming severely limit the available messages.
Then, I noticed people repeating a short, rhyming phrase of political opinion that they could not actually explain in other words, and that took longer to say than the non-poetic version. I think that the appeal is based on our many years of having only oral language. If someone says something in rhyme, the odds are better that they have remembered it right, so we still value it more.
