Daniel Appelquist discussed how mobile technologies can learn from the successes of Web 2.0 by harnessing collective intelligence through user participation, continuous improvement based on user feedback, and providing rich experiences through open platforms and APIs. Key Web 2.0 technologies that could be applied to mobile include Ajax and REST APIs, semantic markup, syndication of data through RSS/Atom feeds, microformats, folksonomies like tags, mashups of content from different sources, and blogging tools.
