I’d assume everybody’s familiar with Flash, correct? It’s the technology that makes sites interactive, animated and video-capable (see Youtube). Well, Microsoft has now released a similar technology to compete against it called, Silverlight that promises higher video quality and better interoperability with search engines.
So far, Silverlight is cross-browser and works for both Macs and Windows (sorry Linux!). You can try it out now and see if you like it.
