When I was last involved (2 years ago), the entire economy seemed to be an amusing dance between get rich quick miners / speculators and a relative handful of early adopters and pool operators siphoning cash off of the former.
My personal favorites:
http://bitmit.net - an auction site that allows you to buy and sell goods with bitcoins.
http://coindl.com - Download digtal files, and pay the content creator in bicoins. Many downloads have "pay as much as you want" pricing. These micro-transactions are only really possible with bitcoin.
Bitcoin Magazine - There is so much drama in the bitcoin world, and they do a great job of summarizing it and making it fun to read about.
There will be a big "Bitcoin Friday" sale on Nov 9th.
Cups and Cakes Bakery in SF will be participating as well.
