If I'm writing it? Prose, easy. If I'm reading it? Same answer.

I've read at least some of every author on both your lists. I'm not the biggest fan of any. Even Shakespeare's sonnets drive me wild. It's like trying to read in Spanish or German. I have enough of either language to 'get the gist' but not to truly understand.

Jack London wrote some poetry that I can read (though none of it would qualify as Valentine's appropriate) and Maya Angelou is a favorite of mine. In spite of the rhyme and rhythm it seems.
