I think the content and niche is good. Although the design is just a standard wordpress template. Plain and boring. There are so many templates out there, i'm sure you could find a suitable one matching your content somewhere.
I have a similar problem with my blog. I use Blogspot and one of their templates. I don't know how to change it, so I'm keeping an eye on the answers to your question. For what it's worth, I like the blog, and I'll be surprised if you don't increase your traffic. Graham.
One of my biggest turn-offs is poor spelling and bad grammar. I know...it's sad...we live in an age where u cn rdce txt to a mnmm but I was bought up differently, you see. Please fix the typo's and sort out the grammar. The world WILL be a better place for it.
Do more improvement with template, it is too white... nice pictures in blog people need more like this
