NeoSmart updated their article with the following note: "This article has been updated to clear up some references to a full-site redesign of Microsoft.com. We do not have any evidence that all of Microsoft.com is being redesigned to take advantage of Silverlight, just large portions of it. Sorry for any confusion."
It looks like Microsoft is getting desperate about the dismal rates of Silverlight adoption by consumers and developers since its release earlier this year. According to NeoSmart Technologies, Microsoft is preparing a fully Silverlight-powered redesign of their website, doing away with most HTML pages entirely. With over 60 million unique users visiting Microsoft.com a month, Microsoft's last-ditch effort might be what it takes to breathe some life back into Silverlight. The article notes: 'At the moment, very few non-Microsoft-owned sites are using Silverlight at all; let alone for the entire UI.'
