The Idea
Annotation stems from the human tendency to underline, highlight, or write in between the lines of all the sentences we read on paper. We wanted to take this online by allowing people to comment on sentences in a body of text, be it a poem, an article, a blog post, a novella, a song, or an essay. Not only that, comments online can be richer than what you can do on paper because you can link to video, images, or any rich supplementary content that is all over the web. People can then vote on the best annotations. The goal is to build a body of knowledge that is grander than the document itself.
