whitehouse.gov has been redesigned. It now accepts petitions for people to vote on. I think this is how our government should have been working a long time ago. Check it out. I saw this on Reddit. 3 petitions are of particular interest to the Atheist community as listed below. I think it is way past the time these are addressed.
