RSS and tagging are key to p2p collaboration over the Internet. Tags allow people to organize the information available through their distributed networks in ways that are meaningful to them, and social networking enables nodes in these networks to interact with each other according to how these tags and other folksonomic data overlap. When productive tags are identified, then RSS is used to monitor where web artifacts using those tags are accumulating, or being aggregated. This presentation will explore some of the ways that tagging can be used productively by people wishing to locate one another in order to discover more about each other's cultural and linguistic backgrounds. The WritingMatrix project will be used as an example of how basing interaction on tagging has enabled students in various parts of the world to interact with one another in the ways suggested here.
