Video is OK but his presentation is fecking awful. For instance, you don't need to say "right?" at the end of every God damn sentence, even if only to reinforce the mouthful of absolute bollocks you just said:
"But the problem is, this... this is only part of... part of the thing... right?"
Also, not sure anyone should be taking design advice from someone who splits the word "Subscribe" into two words, just so it fits nicely into a square.
Gave up watching after six minutes.
