Like the phone book, but in a more interesting order

Aaron points us to the nearly endless listing of website traffic rankings at Quantcast.

There's no doubt that the list is rife with errors, but it's free and fascinating. My two top takeaways:

• It's not one list, it's 43 different lists blended together. So, you might find the #1 craft site nestled between the #9 news site and the #25 sports site.
• It's really early days on the Net. The long tail is still fleshing out, and 99% of the market is totally up for grabs.

Happy brainstorming.
