The only thing I could suggest would be to possibly include more images on your blog. Specifically in the actual articles. But the content is good and content is king. I like that the articles usually deal with topics that are hard to learn about elsewhere. Most places either assume you know nothing about computers (even how to turn one on) or you know everything except their one tutorial. I think it's the step by step approach you've taken that makes it enjoyable.

Having said that, I've probably told you more than I know.
I really enjoy what you've done with the pages. The blog contains a lot of information that will help out beginners when they wish to create their own site. Nicely done!
