Anyone using YouTube through IE6 is seeing a banner saying that support for IE6 will be phased out soon along with likes to IE8, Firefox and Chrome.

How many people out there are still using IE6 voluntarily and how many have it forced on them through corporate standards (usually due to web apps that will only work via IE6)?
