I've been trying to follow the "do what is typical in the language in which you're writing" philosophy. So, in Ruby, I use underscores, because most methods and variables in common Ruby libs use underscores. In Javascript, I use camel-case, for the same reason. In CSS, I use a dash. In PHP, I do whatever tickles my fancy at that moment in time.
