I've lived in Waikiki for the past 2 years. I'm a 15 minute walk away from the beach. Do you know how often I visit? Once a week.
Moving here will not magically make you more outgoing or productive. While I love it here, I lived in Austin and miss the tech culture from the area.
Granted I probably should network more but it's mostly IT, real estate, and tourism industry. There is no comparison to SF / Austin for startup culture.
If you're browsing HN and in Honolulu, let's grab a beer.
