Dive Trips, Scuba Diving (Singapore)

I just wonder why there are only few posts dealing with dive, diving, scuba at this forum.
Singapore as a major travel hub in Asia offers quite good access to a number of interesting diving spots. Furthermore, there are some weekends ahead which can be easily extended to meet for some interesting trips.
And personally, I always prefer to go with known buddies instead of hoping for "not too strange" underwater freaks at the actual destination.

At the ADEX Protected content Dive Expo) in April I collected some interesting offers and asked myself who else from InterNations might be interested and capable of joining on such weekend trips. Or does someone have special recommendations? Does this subject raise any interest at all?
