Rap Genius was just the first step to fulfilling Marc Andreessen’s Netscape dream of letting people annotate the whole Internet. Today, the lyric explanation startup tries to achieve its destiny with the launch of its new genius.it/ prefix that lets you add annotations to any web page.
Just put the prefix before a URL like http://genius.it/techcrunch.com/author/josh-constine , highlight a piece of text or image, and you can append a back story, explanation, context, or extra links. Other users who visit the genius.it/ version of the same site will see your annotation, and can upvote or downvote it, reply, or share the annotation.

Another entry into the “annotate the web” space. It seems like the tech is finally maturing and will be a welcome addition for educational use.
