I use pretty much the same style for my Ruby work. One thing I do differently is replacing %w(word1 word2 word3) with %w[word1 word2 word3] both result in ["word1", "word2", "word3"] I prefer the bracket delimiters since they better indicate the array nature than the parens. In % notation you can choose your own delimiters, so why not use brackets?
