The GPO, however, only prints the full code once every six (six!) years. They've got a room full of people reading and double-checking that they're writing exactly what's in the bills. Very archaic. Someone should apply a modern versioning system so the code is in black and the effects of bills are in red (and blue and green, like alexa or Google Trends does graphs, but with text), so the public can see not just the bill, but what the changes look like in real time. It's shouldn't be hard at all.
I'll bet someone could do this with GitHub by this weekend and have a site up by the end of the month.
