just have patience !!!I agree with you but looking at the subs also shows at least a good chance of how many people will watch the videos anyway.I personally look at the view count as this is what determines the ratings and does lead to creating a fan base. It takes time to gain subscribers as nowadays, it's more common for people to go on YouTube and upload gaming footage etc so it's harder to get noticed unlike say 4 years ago, hardly anyone posted things online and they became big hits as they were the first ones to do such a thingjust have patience !!!
i enjoy YouTube and gives me something to do when I finish work for the rest of the evening. Obviously not the best pay at the moment but I've only started a few months ago so who knows what will Happen. I know nothing will come off it, but it's nice to believe that other people are enjoying my videos 
Views per video is far more important. There are channels with 50,000+ subscribers that barely get 1000 views per video.
I'd say comments. It's nice when people actually take the time to say something positive and start a conversation. But again I suppose it depends what you want out of YT.
