myspace, facebook in hong kong?

Hi,
I am trying to get information about internet usuage but more specific,
social networking websites used in Hong Kong...

1.) Are there popular websites for social networking specific to Hong
Kong? Are sites like MySpace, Facebook, Xanga, etc. popular in Hong
Kong culture?

2.) Comparing tech savy places like South Korea (which is the most
wired country in the world) or San Francisco, California, how would you
say the Hong Kong region compares in terms of people using the
internet?

I'm just looking at the general feeling in Hong Kong for social
networking via the internet.

Thanks for any help!
