Right, I realized that. I guess I don't grok what RapGenius and these annotations are about.
He's an investor.
RapGenius is a YC-funded (and VC-backed) company that lets people annotate rap lyrics. BUT rap is just the initial theme that helps them fine-tune the product. It's increasingly used as a general annotation engine.
So here's a high-profile investor demonstrating exactly that point, that it can be used beyond rap.
But what do these annotations mean? Are they things that Jobs said that weren't in the prepared remarks? Are they some kind of ironic commentary by Ashton Kutcher? Are they explanatory annotations?
