My comment is solely aimed at correcting the misinformation surrounding Pelosi's statement being divorced from the context in which it was uttered. She did, in fact, say exactly that, but the meaning of it is lost when removed from the rest of the speech surrounding it.
Her full remarks on the matter read:
"You’ve heard about the controversies within the bill, the process about the bill, one or the other. But I don’t know if you have heard that it is legislation for the future, not just about health care for America, but about a healthier America, where preventive care is not something that you have to pay a deductible for or out of pocket. Prevention, prevention, prevention–it’s about diet, not diabetes. It’s going to be very, very exciting. But we have to pass the bill so that you can find out what is in it, away from the fog of the controversy."

The meaning Pelosi invokes is not that nobody knows what's in the bill (which had been debated for months prior to this quote), but rather that its benefits wouldn't become clear to the American people until after its passage, when things began to change for the better, the uninsured could finally get insurance, people with pre-existing conditions could no longer be denied, and young people could remain on their parents' insurance plans through college and beyond to avoid financial hardship.
Aside from that, this is a finely-written essay. :)
