I haven't posted much the last couple of weeks in part due to being captivated by Egypt. It's rare that non-violent protest and civil disobedience are so spectacularly successful. From the blog I linked to earlier, how Eygpt did it - a good look at factors leading to the protesters success including the groundwork laid and conditions specific to Egypt. A lot of what's discussed there is also probably a good indicator of whether the protests will be successful elsewhere. A similar look from Salon emphasizes the economic clout of the protesters.
