Wow Paul thanks so much for the glowing endorsement and all the pointers.
I'm blushing! ;-)

I've been on this list for a couple of years, just haven't had time to
engage in it over the past few months.

Over the past year I have not been focusing on China much other than in a
very general journalistic way, and my study of  Chinese Internet censorship
was always more focused on the layer of content-hosting companies than the
ISP layer (mainly because when I started researching these things around
2005, the only research done on Chinese Internet censorship was on ISP
filtering and nobody was taking the other layers of censorship into
account). So I don't have anything to add to a discussion of the latest
developments in Chinese ISP filtering.

Cheers,
Rebecca
