Collaborative writing by small and very large groups

Wikis are perhaps the simplest collaborative writing tool, but they are best suited to compiled and simple co-authored documents.

For more complex co-authored documents we use network-based word processors. While they are limited and slow today, they will improve as technology like JavaScript interpreters, development tools and network speed improve.

For massively co-authored documents, documents with many authors, we need to add structure and social networking features. This class note discusses two sites for creating massively co-authored documents, PublicMarkup and WePC.
