FYI, I've been blogging very heavily on the umbrella revolution at http://bitquant.quora.com/and answering questions on Quora about what is going on. This is focused at explaining HK politics to an English speaking global audience.
One thing that I have been doing is to track the news from Beijing and to see what their reaction is. Right now it looks to me that there is a power struggle between Xi Jinping and Jiang Zemin, and that Xi is winning and tends to be more favorable to umbrella.
I'd like to keep that link here, because I think it would be important to monitor Beijing's reaction, and to have an "early warning" if things start looking bad.
