To be honest, it doesn't look very web 2.0. Not saying it looks bad at all, just doesn't seem very modern to me. Again, that's just me.
I think you should change the colors of the Twitter widget to blend better with the rest of your blog. I would have probably used a combination of blues.
I like the site a lot. The layout looks great -- but it is a bit dark on my screen. Other than that, 9/10!
I like it overall, except the too-harsh light-green to dark-blue contrast, plus the typography needs a bit of a touch. The font size is way too small for all the paddings - creates the feeling of some unused, empty space. So I would say either increase a bit the font or decrease the gaps/paddings a lil bit of a tad only, especially on the home page.
Site looks good.. i think the lastest article section.... teh descriptive font doesnt match with teh background letter fonts please work on it. All the best.
