Do you think that the G20 Summit will do any good for the world?

Leaders of some the world's most powerful economies gathered to "join forces" in order to deal with the financial crisis. They plan to talk on: financial regulation, tax havens, fiscal stimulus, IMF boost, global trade and bankers. On some issues they will agree and on some not, but does the whole meeting represent something useful for the world? Feel free to express your opinion in the comment box below.
