堕落 duolo.com (contextually translated into “debauchery”) is like 豆瓣 (Douban) for food, entertainment and travel; that is, it is a social/sharing site for those things. One gripe I have is that the headings for items or posts are not well restricted; one item is titled “the few things I ordered at YanYangTian.”
The correct url is http://duolo.com
duoluo.com is another bbs which exists for 5 years in China.
