Very nice idea if there was a REAL democracy, but I doubt this will be suitable to the law-makers, because most of them don't want people to know how this process is, let alone know what laws are being discussed, and even worse, who and what did he/she patch...
What you say is very true. Dunno why people downvote a little truth when it's stated clearly.
If what you said didn't have a strong grain of truth in it, then there would be no need for this project. Our laws would naturally be more straightforward, clearly written, and better organized because they're so important to society.
There are some really strong forces that oppose simple and clear laws. Some of them are more natural results of maintaining a complex system. My feeling is that a lot of the code ugliness is due to the selfish needs of those in power.
In HN terms, the current system is Proprietary. This GitHub project is looking to add some Open Source goodness to the mix. I think it's a really wonderful idea, since the very act of shining light into the enormously daunting spaghetti code that we have to live by every day may help to wake people up to the unneeded obscurities, contradictions, redundancies, anachronisms, wastes, and outright abuses of power.
