Add Your Own - Restaurant Wiki for NYC restaurants

(via Many-to-Many) - Add Your Own is a New York City restaurant guide with a difference.  It is a Wiki, which means anybody can edit it and anybody can add their comments about restaurants and delete other people's comments about restaurants.  In other words, it's a collaboratively written restaurant guide.  It may sound like a recipe for chaos, but in practise it works well; malicious people are rare and the system keeps track of all changes so it's always possible to undo flames and other bad stuff. I'd love to do something similar for Vancouver.
