Saeed Moaddeli discusses microblogging services like Twitter and open source alternative Identi.ca. He advocates for making microblogging data more semantic and machine-readable by extensively using URIs and open standards like FOAF, SIOC, and RDF to represent users, topics, places, and relationships between data. Some initial research has been done on semantic microblogging, but more work remains to be done to fully link microblogging data on the semantic web.
