Favourite YouTubers?

Personally, mine are

Vsauce/Vsauce2/Vsauce3: Thought provoking, intelligent videos. These guys deserve more subs. I always smile when I see their videos in Most Viewed.
wibble: The only LPer I honestly bother watching. I think that I may be biased, but that isn't a bad thing as long as I don't go screaming about it.
GilvaSunner: For uploading many video game tracks, we salute you.

I only have a few. What about you?

HATFilms - These guys are awesome and funny and the best place to start with them is the fanimations (King Ashley and Wizard's Kiss are my favourites). They also play Trails Evoultion, Minecraft, Worms Revlution and more.
InTheLittleWood - Even though he's a part of the Yogscast now, he's still great doing his Let's Plays. He's even doing Rayman Legends and Infinity when they come out.
OfficalNerd3 (Can't do the cubed sign on my laptop) - Deserves more subs. He's just too witty and funny for my own good. His Assassin's Creed Revations vid was my first video I watched and is also a great start.

Smosh- I know a lot of people think they aren't as funny now, but I still find them hilarious.
Tobuscus- I just find him funny
Daneboe- Same reason as Tobuscus
Animeme- Particularly the Rap Battles
Pieguyrulz- He makes a lot of good points in his rants
ERB- Same as Animeme

^ I like Tobuscus Adventures sometimes.

Danisnotonfire and amazingphil

I love them and they have many combined channels

I like xRpmx 13 - a Minecraft YTuber

Just to name a few...
supermariologan: Funny plush videos, kept me happy during tough times.
Vsause: Same reason as Nibelilt.
PewDiePie: HILARIOUS!

I forgot to add Caddicarus, he gives hilarious PS1 reviews.
