Considering that Kynamite is one of 5 members of the "London 5 Way" video, which has over 28 million views on YouTube, that he graduated from The London Contemporary Dance School, and that he went on to sponsored by Adidas and featured in a full size Adidas billboard in central London, I presumed he would be classed as a notable individual. I think the problem is that Cwalk as a dance style is still quite unheard of, but I guarantee you that every Cwalker in the world has heard of him. His video is the most famous Cwalk video of all time and the first to appear on YouTube if you typed in Cwalk. Within Cwalk, he's a superstar.
He is one of only 5 Cwalkers in the world to be sponsored by a major sports brand, that was a huge step forward for Cwalk as a whole in terms of raising awareness of its existence as a style of dance. Within the circle of Cwalk he's very notable indeed, the only reason you haven't heard of him is because Cwalk as a whole isn't very popular, but he is to Cwalk as Ice Cube is to rap music.
