feeds Weblog-publishing tools Wiki or forum software, etc., to support user-generated content Semantically valid XHTML and HTML markup Microformats extending pages with additional semantics Cascading Style Sheets to aid in the separation of presentation

and content REST and/or XML- and/or JSON-based APIs Mashups, merging content from different sources, client- and
