So what's Rhiz.eu?

An intercultural meeting place developed to give its members an easy and fun environment for communicating and collaborating with each other. It takes its name from a botanical term, rhizome, meaning ‘a usually underground, horizontal stem of a plant that often sends out roots and shoots from its nodes’ (Wikipedia): the term is used metaphorically in the social sciences and new media to describe social structures that are non-hierarchical, non-centralised, self-regulating, and formed peer-to-peer. Rhiz.eu was created by the European Cultural Foundation (ECF).
