The point of this annotation was for someone who disagrees with the author to offer a point by point take down in the context of the original article.
You could understand the article (at least the view the author wants to promote) just fine without the annotation--the annotation provides a counterpoint that systematically undermines the premise of the article. [edit spelling]
Agree! I was going to reply to some of Sam's comments, but stopped because this is not at all what Genius was designed for and my reply to his comments wouldn't fit the UX.
Ah, that's the first use of the annotations for this that I've seen. The only other "news" I've seen on Genius before was statements from Genius or a16z, and the annotations only provided more in-depth explanations of the text.
