Sweden.se, has had a makeover. I have had a visit and it is fantastic. Visually and practically, it is a joy to use. I've already spent too much time looking through it!
The website is just part of an overall digital brand/design initiative covering all of the country's online operations. Söderhavet, the firm doing the work, has posted a great explanation of their ideas and tools in providing a consistent identity for the country. It, too, is worth a read.
