From Netbusinessblog 8 reasons why the masses love lists.

    1. Instant Knowledge
    2. Requires Little to No Individual Thought
    3. Lists Have Authority
    4. Easy to Memorize and Casually Mention in Conversation
    5. Lists are Skimmable
    6. Mobs Like Uniformity
    7. Lists Have an Ending
    8. People Like Counting

Hmmmm - not sure if I buy all of that.
