Some sites integrate the Genius JS code directly but they don't have to. As a user, you can freely annotate (nearly) any page on the web with the bookmarklet.

Some sites integrate the Genius JS code directly but they don't have to. As a user, you can freely annotate (nearly) any page on the web with the bookmarklet. I made numerous annotations on the famous Bloomberg "Code" article which you can see on the page at [1] or in summary from the page at [2]. For [1] to work, you need to either run the bookmarklet or Chrome extension. This isn't the norm though; most annotated pages can be viewed directly from the genius link, and you can even link directly to a specific annotation, for example [3].
