These two laws that are before the American Congress and Senate, are designed to stop piracy on the internet, and protect intellectual property. On the surface these appear to be good things, good laws, that help writers and creators etc. I've already heard a talk radio host try to defend them on that basis, and this host is often against government regulations that restrict freedom. So my first inclination was to try and explain to him why these are draconian laws.
My mind works like this: why bother trying to do something if someone else has already done it, AND done a better job of it. Thats why if you come to my blog, you will note that I like to "share" stuff that is already available. That could get me in trouble with these laws, not that I am stealing material, I'm just trying to show people where to find good information. Laws like this in the US may eventually come to Canada, I guess that too is sharing and very worrying.
Let me share with you the best explanation I have seen thus far for these two laws. Its on a site I have mentioned before: The Khan Academy, it's absolutely excellent. Look here.
