Until now, my favorite Youtuber is GFX Mentor who is an expert in Adobe PS, AI and Illustrator. The way he teaches and attention to detail is extremely appreciable. I learnt Adobe PS, AI and Illustrator without spending even a single penny and that too while sitting at home. A decent personality easily reachable at Facebook and Insta.
Prays for him that he may achieve the peak of success.
While this is subject to change, my favorites at the moment are Braille Skateboarding, Playstation Access, and Davie504. Life has been a bit complicated recently, so watching lighthearted channels has been a major help.
For years I just used it to watch comedy clips from established shows. But this year I've really gotten into actual Youtubers and subscribed to some nerdy legends like Lindybeige and Scholagladiatoria.
