1. Whenever I see somebody's list, say, of 5 good reasons why McCain should be elected president, I can be almost certain that it'll be followed shortly after by a list of 5 good reasons, maybe formulated by the same person, why Obama should be elected.
2. It's a fact that, in our computer-oriented society, we're accustomed to numbered lists of items. [I myself am a culprit at times concerning the use of lists in my writing.] We should realize however that, while this linear style of expression might appear to be clear, it is not necessarily valid or convincing.

For example, I can think of one good reason why I don't believe in God, namely: He doesn't exist! But this list is surely too short.
