Agree that you need a nice looking banner and logo. That is a free WP theme you are using, available from their directory so the site looks a like thousands of others that use it.
Overall the site loading speed is good, it's simple and easy to navigated. However, it seen incompleted to me. Agree with the others that streamline the design needs to be improved. Especially your blogging niche are so popular, you will need to add something fresh or additional to be able to stand out.
Hi, Just looked over your site, the theme is great... fits the whole tech idea. But a lot of links are not working in the nav bar... Greetings, Maik
