Go here to see a real-time map of Twitters--short messages from random people who are letting us all know what they are doing. Warning: it's hypnotic. You can see the different Twitters popping up nonstop all over the world...people in the middle of the night, just leaving the house in the morning, getting ready to go to bed, pondering. The map isn't that good for China--it kind of looks like everyone is somewhere around Wuhan.
But watch for awhile and you'll recognize the names...Isaac, Flypig, Engadget Chinese, Sinanews (!) [Update:] Fons Tuinstra, and so on. You can sign up for your own account here.
