Unfortunately your question is akin to those such as "how long is a piece of string?" All those who do answer your question believes that their method is the simplest or fastest way to accomplish the task and for them it probably is.

The section in Pablo's tutorial PDF is pretty simple and probably should be the one you use to keep the semantic people happy.

If you don't give a toss about the semantic people just use one <p> per stanza with <br /> at the end of each line and use your own <p>&nbsp;</p> between stanzas.

It's not what I personally use (nor Pablo's method) but since I do know "how long a piece of string is" I am happy to keep my method to myself.
