Oh, so that's what a poem's supposed to look like! I didn't know...
From The Associated Press:
"A poem sometimes possesses rhyme or meter, though this is not necessary," Keenan wrote. "A poem is typically free from the usual rules of grammar, punctuation and capitalization." In a footnote, he cited testimony that before "World War Two, a poem almost always had rhyme or meter." Now, "the popular definition of poem has become much more lenient."
