Revolution in Tunisia

I haven't commented much on Tunisia, because I really don't know that much about it. But the people have revolted and managed to kick out the president. See chronology of events. The former president is now in Saudi Arabia. And other people in the Middle East are starting to think, "hey, maybe we could do that too." It's probably the only way Egypt will get rid of Mubarak.  If Tunisia can do it, why not other countries?
