The Purple People movement is an Italian group, without leadership, agenda, or funding that represents the anger many Italians feel towards Silvio Berlusconi. Apparently founded on facebook, it has resulted in large protests in Rome, calling for the removal of Mr. Berlusconi. Members of the movement are identified by their use of purple. The BBC describes the Purple People Movement as "a political movement outside of the political system...They appear to be a genuine cross-section of Italian society that has come to the conclusion that Mr Berlusconi is bad for Italy's health." They arose beacuse: "Italy's official opposition is weak and divided and is not doing its job...we have to do it for them".
This informal organ (vox populi) is made possible by the smart use of social media (facebook, txts, etc). A similar English movement in the early 17th Century called The Levellers, also took advantage of existing technologies in the form of petition and pamphlets. "The levellers were not a political party in the modern sense of the word, and did not all conform to a specific manifesto...The Levellers had no coherent agenda...there is no record of their having sat down together to develop a manifesto", they came together over a loose set values focusing on anti-corruption, greater suffrage, religious tolerance, and a clear judiciary.
Even farther back, the Plebians, during the gestatious days of the Roman Republican staged five secessio, wherein all plebians simply left the city, "an informal exercise of power"
Can governments be structured entirely in this fashion? I.e. can government be informal?
