Hey man - I new to this to0. Been on YouTube for just under a month. I think you've got to use your Facebook at least at first. Yeah, I know it's a little spammy to hit up your friends and family but they're going to subscribe and at least parents ect will share your videos. I also kinda looked at it like this - if my family and friends won't watch what I'm doing and I'm not ok putting what I'm doing in front of them how do I really expect total strangers to subscribe? I guess it's a personal call for everyone but I felt like it was totally something I was ok with. When I launched I probably got my first 20 or so subscribers from posting to Facebook and then having my girlfriend post to her Facebook etc.
To me it seems like the best way to get the ball rolling. Anyway, after Facebook I think participating in forums like this will help. You'll make friends and gain some subs/collab opportunities on here.
I clicked on your link but don't see any videos so it's a little hard for me to give specific advice because I don't know what your channel is about. One other thing I did is I reached out to some people I knew who were bloggers that blogged about mom and kid stuff (I have a kids channel). And they were kind enough to blog about my channel. That got me quite a few subscribers.
Then I think just interacting with other people on YouTube. Posting replies to people's comments ect.
Anyway - good luck with your channel. Hope that helps!
Matt
