C2C abbreviates citizen to citizen - formation of basic e-democracy units especially to lobby or campaign during an election, e.g. advance municipal initiatives or party platforms, or act as citizen journalists documenting under-reported news.

While blogs and mailing lists and hybrid web services like yahoogroups are still the most popular, the most effective C2C interaction is increasingly via mediawiki-based services and tikiwiki-based services like openpolitics.ca itself.

C2C typically relies only on public Internet technologies, signal infrastructure owned by citizens themselves, and open content. All C2C efforts are based on platform-independent and open content, e.g. the living ontology project by Efficient Civics Guild. The use of open data formats is especially important.

Interaction of C2C, G2C and G2G can be represented as a tensegrity of duty.
