It looks like you have a really good handle on the content of the site, but you have some grammar errors that distract from that great content. I would consider having someone proofread it really quick to fix those small mistakes. Your theme is nice and clean, but it doesn't really stand out to me, I might try getting something more unique.
The template is - well you could use a new one that is unique. The one post is good. If you develope more content along those lines and get a good design. You could get some readers.
You've got a lot to work on. What's your goal with this blog? Is it an information blog or do you intend to make money out of it or? Once you set your goal/s in place, it would be easier to give you proper advise on what you should do for your blog.
Nice-looking blog. It's a little plain to me, but maybe you could add some graphics if you want. Good luck!
I agree on two points: 1) It is a little plain. The subject matter means you will have large chunks of text, so something to make this easier on the eye would be good 2) Pics need to be added, just to break up the masses of text. Nice enough blog though.
