I think most demonstrations are there to make the demonstrators feel better. So changing your Twitter avatar can make you feel better - it works just like the real demonstration? Except that if you go to a real demonstration, maybe you can make some real friends. You don't actually meet anybody by changing your Twitter icon. But that is another side effect - the original "I want to do something" works both on Twitter and on the street.
