A great place to meet other divers, is your local clubs. I am a member of Dolphin Divers of Sacramento. It is a social club that does not require a ton of maintenance or effort. For example, this weekend we have a Abolone Dive scheduled at Ocean Cove. Yes they it is a free dive but other members SCUBA and hunt for fish and/or discovery. Its a great place to meet some good people that share a common interest. If you are into photography, AIM or Seahourses are other local (sacramento) clubs to become familiar with.
Dolphin Divers have a meeting on the third Wednesday of every month. It is not mandatory you go to them, but its a great place to socialize and meet other divers. This month it is on the 17th at 7:00 at Round Table Pizza in Orangevale. Stop by and say Hi!
