Someone I know and respect just noted:
Friday's planned protest will reveal a lot. El Baradei supports it, and the Muslim Brotherhood has announced it will participate. Mubarak has put his most elite force on the streets and has cut off access to internet, twitter, etc.If President Mubarak is overthrown his replacement might not be as friendly to the US. What it might mean for peace in the Near East is up for grabs.
