Scientific experts concluded today that, much like how air pollution created by people is the only reason for global warming, (and not that completely bizarre theory about the earth expanding, which has no basis in reality), people are also responsible for the current migration of the poles.
They have concluded that the reason for the poles slowly changing places is peoples excessive use of sites such as Youtube and Twitter, although at this time they are not sure exactly why this is, only that it is.
Therefore, the US government will be banning these and other sites contributing to the problem, immediately.
There is no need for alarm, you will still be able to share information, videos, etc., the same way you have on these other sites, you will just have to do it on a government created site that will give them the access to monitor all activity to make sure that no more harmful information is exchanged. (Users of the site will also pay a nominal fee to the government for the use of it's site).
Research is now underway to determine if social networking sites such as Facebook also contribute to this problem.
We will, of course, keep you properly informed about any developments in this story.
