I like the site, I feel it has a sharp and clean layout.
I am not a fan of scrolling div’s, but that is a personal choice.
I think the home page wastse some space. You ask for user input for what content they would like, I don’t think you will get much of a responce, I would just list your articles there. If you get your traffic from SE they will be there becouse they like your content, if you dont have the content they want they will never find you…
The next section is about your site…no one cares. People care about them and there needs, not you and your needs (or accomplishments).
