Getting Traffic is Tough

I told you about my website, Aaron's T-Shirt Review, a couple posts ago. Well, I'm having a tough time getting much traffic to it. It has been increasing in each month that the site has been up, but it's not where I would like it to be. Google is by far my highest refferer right now. I guess I just need to keep making content, improving the design, and tweaking things. If you have any tips, I would welcome them. I'm off to research some traffic techniques, and I'll post the results sometime in the future.
