I always thought the core service was a pretty good idea, and an exit by selling to a music company seemed feasible...lyrics are fun, more importantly, people are passionate about music. So passionate that that they're googling specifically for these lyrics, and also, they have the lyrics mostly memorized. So annotating, and reading those annotations, is a delight.

But everything else? Such as news and literature? That's a different story. Unlike contemporary lyrics, much of the literature that people want to see annotations for -- i.e. the kind of stuff that's studied in literature class -- is already "annotated" by experts, or at least in the form of "Spark Notes", an already popular service. And news? Sorry, as someone who has worked in the news business, there's less of a collective passion in the exact wording and phrasing of a news story than there is for literature/art that captures our collective cultural attention. For obvious reasons.

And this embeddable annotation system, which presumably require the site owner to enable...how is that system different than an inline-version of Disqus?
