#1 Hint, make good videos! And to get subscribers, make some kind of theme. I have a couple OK videos and no theme, so I have WAY less subscribers than you but a lot more views. My own tip to myself is; make something that you would share with all of your friends if you saw someone else make it. Right now I'm riding on my dog videos since I'm not in the Navy anymore (which is sad because my most viewed videos are navy videos). I've had a video make it onto an Animal Planet TV special, but it still didn't get me much extra exposure on the net as far as I know. Just try to think what the world would randomly search for or want to see, and then make it....
