Stackoverflow doesn't have a Chinese version - what domestic site is popular there? (And how many questions does it have?) I looked at Segmentfault (CN) but I can't see any total number of questions - but if I refresh StackOverflow the 5 most recent questions were all asked within the last 1 minute, whereas on SegmentFault the 5 most recent questions were asked within the last 20 minutes. Although it might be biased by the current timezone.
