Nokia has announced WidSets, a phone manufacturer-independent Web 2.0 service, that automatically multicasts preferred RSS feeds and user-generated content. WidSets allows users to build a Content Library, choosing from RSS feeds to blog posts to photo uploading sites that are multi-casted to any new generation Java enabled mobile device. Widsets Templates allow users to include their own websites or blogs, for their own private use or that of others they choose. Collaborative filtering allows the community to enrich the Widsets Library by providing suggestions for new content that a user did not know about. The WidSets User Interface uses a process of "choose and set" designed to make Widsets operative within seconds. Signing up to WidSets is free of charge and using WidSets is optimized for minimal data consumption.
