It's not a revolution of course - but the decision of 45% of Scots to vote for independence has created a new political dynamic whose end none of us can foresee. I travelled from Shetland in the north to the borders, Islay in the west to Edinburgh, Dundee and Aberdeen. One of the most memorable encounters was in Shetland. I tried to encourage an older local man to give away his political views.
"So is it Britain's oil?" I asked. "Or Scotland's oil. Or Shetland's oil."
Without missing a beat he said: "No, it's the oil companies oil." Then he added: "The bastards."
