What if we flipped this all on its head? What if we hosted our own data, and provided APIs for all these webapps so that they can use our data? I can imagine that to be a substantially cool use of RDFa/Microformats and whatever metadata/semantic web technologies you prefer. Isn’t one of the points of the semantic web to make decentralized information meaningful, retrievable and mixable?
So instead of having our own websites aggregate our own data from other people’s websites, we’ll let other people use the data from our own websites. Photos, meaningfully tagged, can be pulled in by Flickr via our own personal API, if you will. We provide the structured data, Flickr provides the functionality. The sharing. The social. Why not?
Personal publishing platforms like WordPress, Drupal, [your favorite here] could be extended to make use of microformatting, RDF, etc. and provide tools for syndication, as we now do with simple blogposts. Services don’t need to host our data. They only need to do cool things with it.
