Jshop is a free allround theme, which was created for simplicity. Its a non-nonsense theme, and even a great basic template if you want to customize it. The theme is great for anyone who are looking for a theme where the content is in center and where the focus is not shifted towards flash and colors.
We think this theme would be a great match for technical blogs.
