One more "geekCred--;" for letting WordPress (or whatever) convert two '-' to a single '–'.
More on topic, though: I don't think anyone is seriously claiming that both solutions are equivalent or easily interchangeable. For me the simple and 'process the files once' approach makes a lot of sense and even seems more transparent than a big beast like WordPress. Whether Jekyll or Blosxom - something that feels less like a CMS and more like a way to write simple texts.
