I can't attend, but good luck from Hong Kong! AFAIK this will be the second Asian LW meetup. I was also unsure if HK had enough rationalists for a meetup, but I managed to get 3 of us LWers together, and we enjoyed an interesting chat about OpenCog and other topics... So it's worthwhile even if you can only get a few people. And of course, you have to start somewhere.
John Teddy asked me to post the following info for a Less Wrong meetup he is organizing.
Where: Starbucks, Carrefour Mall, the Zhongshan Park Store, near the Zhongshan Park Station, Line 2, 3, or 4, Shanghai, China
