Hi I think the layout of the site is good and you have a decent amount of articles that are written well. The only criticism that I have is the theme of the site which at the moment looks a bit boring, something more colourful could improve the look of the site.
It's good idea for: 1 Sharing useful articles for who are interesting about site perform. I love it... 2 With a question gadget for voting is a good idea. 3 Fully with decent articles. 4 Show contact box for collecting visitors's message. Not bad concept. Anyway, I have some comment: 1 Don't you allow reader leaving any comment on article? I think if you do it so, it will help your site getting traffic. 2 May be you should add more videos, pictures, or any widget for make your site lively. At present, it looks plain. 3 Show you author profile for reaching who you are. 4 Embed some related links on each of your post and highlight color for notice is easily that would encourage for more clicks. That's all my point. Michael Leng
