What can I do to get more of an audience to view my YouTube channel?

[WhatIDK]

My channel is http://www.youtube.com/user/productionsofjordan and I upload on a regular basis.

I'm just wondering what else I can do in order to grasp a larger audience although I have reached 400 subscribers in a month of dedicated vlogging. Do any of you have any ideas, or do you know any youtubers that may feature me?

I already have accounts on social networking and media sites, including facebook and twitter.

Thanks and thank you for taking the time to have a look, if you do. I really appreciate it.
I am totally against Sub For Sub by the way, so no point suggesting that. It's illegitamate and wont really get me anywhere.

I will take a look at your channel too if you want me to though and if I like, I'll sub!
