In a parallel world the whole web is served as XML and XSLT directly from the databases, or from rss authoring software. Web servers only serve the blobs like images and other media. Content Management is done by combining rss feeds according to site hierarchy via an enhanced OPML dialect, also parsed client side. One or more feeds per page. Some pages show only the newest entry, others show the first ten with pagination, or all entries. This is configured via the OPML dialect. The data sources of a website can be completely federated. A machine readable licensing system enables integration of content from third parties on your site — without any backend changes! Social networks are basically thousands or millions of different sources in one huge OPML file plus some intelligence in the XSLT. Efficient caching on the network allows for very small and cheap servers for every content creator. Even your tablet could serve your feed.
