No, it's not a drug, it's the Semantic Web :P

Freebase is sort of like a structured wiki. In that, anyone can add content to the system. What's different, is that you can also add and define your own "Type" which are a collection of metadata. User generated content is quite common, and Freebase actually sucks in a ton of information from Wikipedia which gives it a huge base of content to start with, but this concept of being able to add/edit/organize higher level structures and metadata is new (tagging aside...).

I had great fun fleshing out entries for Drupal and the Drupal Association, figuring out Company, Software, and People types in the process.

OK, OK, I admit -- filling in the Beer entries for Hacker-Pschorr Weisse and the Hacker-Pschorr Brewery were actually more fun :P
