I woke up this morning to the news that Egyptian dictator Hosni Mubarak had resigned. Sadly, he bypassed Egypt's constitutional succession processes to turn over power directly to the army. But the important bit is done: the tyrant has gone. Now Egyptians have the long hard task of building a democracy ahead of them.
Meanwhile, this has put the Arab world's other dictators - and dictators everywhere - on notice. The people are angry. The dominoes are falling. They are next. They can either reform or be driven out by the people.
