Honestly I think video tutorials are shit.
I prefer a text tutorial any day. Shit's easy to search and come back to.
And you don't have to fucking play the video at 2x speed just so the person can finish 1 sentence. Even worse if he has a shitty mic, or god forbid, a 13 year old.
Only time I'm interested in videos are mainly for the concept angle. Not so much "do this, do this next".
Gleb tends to be more concept oriented and less hand holdy.
There's just not enough text tutorials of anything in general though.
