For me personally, I don't get into blogging or social networking or whatever due to that I don't really have the time.
Nevertheless, I can give you my first impression....it didn't impress me nor did it grab my interest to look into it further.
The header/logo is okay but could use some visual improvments. It just doesn't appeal to me. Not sure why you would change the home header to a different header for the inside pages.
The blog page doesn't even match your main site. People like consistancy once they land on your site so they don't have to guess where the menu is at or wonder if they are on the same site or not.
Code, although you did use divs for the layout, you didn't use any heading or paragraph tags. Bold tags are out and so you should use <strong>.
I could have missed it but I didn't see where you defined a font-family because the font is inconsistant throughout.
I don't think this concept is anything new but keep in mind that I just don't get into that stuff much. However, this doesn't mean that you should stop or move on. It just basically telling you that you still got work to do.
I do like the title/domain and the motto/tag line.
