I have watched the Libyan and Tunisian revolutions. I can confirm that the Tunisian one was led by a particular part of the population (mainly the poor and forgotten). In the Libyan revolution, I saw all kind of people from different background, social and economical levels. Libyans are friendly, and generally quite generous and kind. That being said, I wouldn't be surprised that a good part of the rebel army is made of regular citizens.
