It's not really their innovation. Sorry to be indignant in public,
but crit.org has been around for a long time. Check it out. Or,
better yet, just go to

Notice those little red markers? That's an inline third-party
annotation. Third Voice's software looks slick, but it's not
correct to say that it was first.
If, on the other hand, we're talking about the idea of annotation
rather than a Web implementation, we'd have to go way back to
Engelbart and Nelson.
