Very clean looking site. The menu is a bit odd in that it does not appear as logically as many sites. I like the way it is very minimal and does not take up much real-estate, though.
I really like the content sections (articles, site news) templates. Looks very nice and focuses the attention.
I would bring some more information to your homepage so that the user does not feel that this is all there is to offer.
Hope that helps.
