Here's a comprehensive list of websites we use in Hong Kong. Surprisingly many of them belong to a company called GeoClicks which happens to run a number of websites for expatriates in Hong Kong.
GeoExpat.Com: They have some amazingly helpful forums, classifieds and directories for Hong Kong.
GeoBaby.Com: Something for everyone who is either pregnant or has young babies. Amazing to watch so many baby groups start up, meet and flourish.
Hemlock: The funniest man in Hong Kong.
