Nice to meet U-tube

I have always heard people talk about u-tube, describing great videos they had seen and which were really funny and just had to be watched. I had read an article recently which described the political force that U-tube was becoming, making and breaking campagns, particularly in America, but also in Australia, demonstrated by the use both Kevin Rudd and John Howard made of it. However, up to this point, I had never actually viewed any U-tube video myself. I began with some light entertainment - singing, dancing lego men, which, I admit, were actually quite amusing.
