This is what's the most frustrating thing about YouTube. There is just no way to predict what will make someone burst onto the scene. Like, that kid just pops up huge because of a random picture and in a few days he'll be no one again. Meanwhile you've got a whole forum here of people working their asses off, with the capability and drive to actually build something substantial if THEY got that sudden exposure on the big level, but they don't.
When you're sitting around, working on your videos and whatnot, there's a part of you that really does believe that as long as you put the work in and make something good, you'll get noticed and you'll get big. Then some random kid working a register at Target explodes for no discernible reason. It's infuriating.
