Skype has long been one of the few respected applications to use a peer-to-peer infrastructure for its services. Moving to the web will mean divorcing itself of its heritage. But while this isn’t great for peer-to-peer technology, it is good for the tech world in general. Skype clients have long varied platform to platform, with Linux and Mac usually getting shafted compared to the PC version of the software. When Skype was bought by Microsoft, the assumption was that Microsoft would do little to fix that, perhaps even encouraging the sad state of affairs mac and Linux users (like me) had to suffer through.
A move to the web, however, means a more portable future. If the client complies to HTML5 standards, it will be playable on any browser and any operating system. That means that the future of Skype is much, much brighter than we worried it would be.
