I will be there too as it turns out.
We could announce a Stackexchange Dinner where people from the SE community gather. Here is the Plan:
finding a neat restaurant around the bund, not too crowded
finding a nice waterhole for after dinner drinks
printing flyers for the event
distributing flyers on the conf
meet at the restaurant chat ...
I will be there, but I am collecting the needed information about the Visa process. It is the first time I go there. besides, I am willing to meet some stack exchange active members personaly, to discuss what's new and what we should prepare for the future... cool :D
