I think that it's too simple. Mightbe create some custom theme for your blog. Now it's nothing special.
It looks good! simple and professional. I think the only thing that doesn't look good there is the logo.. good luck!
The blog loads fast and easy to navigate.You had added some useful resources but need a good template since it looks too simple now without no designs and attractive color schemes.
i love the simple layout. nothing too flashy. it looks wonderful. i have never been a huge fan of the archive, but that is just a personal opnion. yet, maybe you could replace it with most popular articles or something the articles are wonderful. in fact i am still reading them! EDIT: found some grammatical errors in the articles. you should really proof read them thoroughly before posting for example, take a look at this: doesn't make a lick of sense to me.
