I move to Hong Kong in November, and I cant wait. I have been spending about three months a year in Hong Kong over the last four years and now finally moving for good (well at least 3 years).
Hong Kong is a fantastic city, and it depends what you are looking for - fantastic restaurants, great shopping and great people.
If you narrow your subject down slightly, to living, shopping, travel etc, I can give you some limited advice. Although this site will give a lot of info, I have spent many an evening pulling info from the forum - it is an excellent resource.
