“UX Specialists” are killing web-design.

Is the user expecting to read an article?
If so, then they will simply be blind to anything that isn't the title and text of the article. If they do notice something that isn't the article, you've probably intruded on their experience --- either with an ad, or a fixed element, or a sudden splash page "subscribe for more great content" ... and they don't care about the four CSS effects that will trigger on parent and child elements in your nav on :hover. They won't notice.
So get over it! Design simple pages. They'll load faster, break in fewer browsers, and probably convert users more effectively.
The site that won the competition is slick, cool, and genteel. Very effective, very appropriate for a government.
That being said... who voted this Site of the Year? Just because people who don't know anything about web design give out awards doesn't mean they are valid or credible.
It seems like a pretty big leap to go from that misguided award to the conclusion in the title.
