Google Code is running a pilot on user-contributed notes to API documentation, currently enabled on a handful of products, including Google SketchUp Ruby API! The goal of this feature is to provide a richer documentation experience for developers, similar to that offered in open source projects such as php.net. “We invite you to participate by adding notes, insights, or code examples to a particular doc. Your note may take up to 24 hours to appear after you submit it. All notes will be moderated to ensure they provide a useful contribution to topic to which they’re attached. Requests for help with API shouldn’t be submitted as notes, but should continue to be posted to Google SketchUp Developers Google Group,” explain Google.
