A discovery I just happened to make - there is a bug (cross-linking error) in the Google Code API documentation. Check out the page,

http://code.google.com/apis/feedburner/

The links to the Awareness API and the Management API are swapped. The link to the awareness API takes you to the Management API reference at http://code.google.com/apis/feedburner/api_reference.html and the link to the Management API takes you to the Awareness API page at http://code.google.com/apis/feedburner/awareness_api.html

hehehe… I really find it interesting to discover such errors with official documentation.
