I subscribed and having been liking the videos as I watch them. I used to not subscribe or like any videos but then I started watching videos on YouTube instead of watching TV because I would rather watch some dude on a dozer build a trail through the woods than watch anything on regular TV. Like and subscribing is how those people are all judged by YouTube and from my understanding the more of all that they get the more money they can make from ads popping up so I do what I can to help common folk make videos I like. It ain't hard to do.
