Zachary Kain ☯: @BarnabyWalters I use <pre> for poetry, since it is pre formatted text. I don't know if I'd ever warrant using a <br>

Zachary Kain as pre retains all whitespace it might be dangerous to use it for poetry — e.g. preserved indentation, lack of minification ability. In poetry’s case, br is more semantic — it represents the presence of a line break. Also you don’t get wrapping (although you may want it).

As usual, the “read the spec, make up your own mind, be willing to change it” rule applies :)
