i'm curious to see whether this will happen, i've heard before the points you mention about Zuckerberg studying Chinese and all that, but as you say I don't see how FB can compete without spending at least 50% of their resources on China, considering the fact they already have massively entrenched incumbents (QQ/Tencent, renren, etc). i've also heard (from people more knowledgeable about these things than i) that Chinese gov is big on internet protectionism and co's like Baidu are heavily incentivized to oust the competition. anyway, this is just one tech-aware Beijing-based expat's opinion, FB getting a bigger market share in China would certainly make my life easier...
