it's the timing more than anything else really.

I know I personally check out everyone's vids once, and if I liked what I saw I'd comment + subscribe, if I didn't, then I'd wait a while before watching another one of their videos.

it feels like there hasn't been a whole lot of great stuff coming out now, there's been a few exceptions, but not a whole lot of stuff that's not been done before, sometimes it feels like everyone's doing the same thing at the same time.
