    He will be online today from 11am EST/4pm BST today. An 
    important caveat: the live chat is subject to Snowden's 
    security concerns and also his access to a secure 
    internet connection. It is possible that he will appear 
    and disappear intermittently, so if it takes him a while 
    to get through the questions, please be patient.

Hah, nice. Reading that just made me smile. Loads of people are going to be patiently watching out for the lag, for the possible periodic disconnects/reconnects, and they will be vaguely internalizing why Snowden has to do this. And this is pretty mainstream news at this point, people are going to be on edge listening for his words. I like the cyberpunk feel of these happenings. We live in interesting times.
