豆瓣 (Douban, founded 2005) is China's nichest social platform — book/film/music ratings plus tens of thousands of user-run
小组 ('groups'). Famous ones include
豆瓣鹅组 (entertainment gossip), 985
废物引进计划 ('elite-school washouts club') and
抠门男性联合会. Slower and more text-heavy than Weibo, Douban groups have outsized cultural impact: many internet trends originate there before spilling to wider Chinese social media.
