Thanks @jarvie : )
It was Zach from Crypto Coin News. https://steemit.com/@cryptocoinnewz
He only stuck around for a month. He does 3-4 youtube videos a day and would always say to follow him on twitter for more up to date information and then when he got onto steemit he was plugging that too which made me think, what is this steemit?

He covered steemit in a couple of his videos but it still wasn't enough to really know what it was about.

I'm sure it's not the same youtuber as yours but I'm now intrigued as to who motivated you...
