I think there is one of these already but I'm not sure. If there is a thread like this already, then the mods can lock this.
My favorite youtubers are: (not in any order) smosh nigahiga RayWJ kevjumba Annoying Orange theDOMINICshow (d_trix) and my most favorite: Jenna Marbles
I don't watch much YouTube but when I do I either watch awesome soccer videos or Smosh and when I was younger I watched allot of Annoying Orange yayayyyyyyyyyy
I mostly watch Minecraft-related stuff so they're usually BlueXephos (Yogscast), CaptainSparklez, AntVenom and ipodmail. I also watch some pewdiepie for Happy Wheels.
K the count of my faves is encreasing so here are my favorites: twd98 captainsparklez minecrafted smosh raywilliamjohnson thesyndicateproject machinima 1crazyfoxx1 TheAdmiralKJ Xximmortalexx Wolfen16
