MySpace may not need any more chaos on its festively designed pages, but with traffic numbers down it could probably use some good news on the apps-development front, not to mention some good apps. To the rescue: Microsoft. On Monday MySpace announced that its Open Platform will support Silverlight, Microsoft's cross-browser, cross-platform implementation of the .NET Framework. (This runs the table for Silverlight, by the way, putting it on iPhone, Android, Blackberry, Sidekick, Palm, Nokia, and now Windows Mobile phones.) The SDK will be available from Microsoft's CodePlex site on Thursday.
