Tsquared, I'm afraid you're very correct. However, I can my advice on what I think sets good LPs apart from the bad ones. The thing that matters most is quality - and I'm not talking about HD videos here. Basically, the videos have to show the more exciting parts of Minecraft over the less exciting ones. (i.e. Spelunking with mobs and lava over just branch mining) Another factor is diversity. An LP about just building things, or just mining, or even just fighting mobs just gets monotonous after awhile. I confess that I suck at both of these, but I'm getting better. However, there's still a chance for me to get noticed. Advertising my channel in my signature on the MCFs and making a thread about my LP increased my views dramatically. However, once the original rush is over, you just have to rely on subscribers and people sharing your videos to bring you more attention. The hardest part, in my oppinion, is making quality videos. That's my two cents.
Also, I want an honest answer to this question: Are my videos kind of dull?
