Friends introduce you to other friends, so there's a positive feedback loop. I have several engineer/startup buddies that I usually hangout with once a week, all about 23-30 years old. A couple of us would probably do something low key (hang at someone's house + eat) this or next weekend. If a plan does get put together, you're welcome to join! Just ping me (email in profile) and I'll send you the deets! Another easy option would be to ask people whom you work with to hang on weekends (hiking is an easy activity, BBQ at the park also works). Go to where most of them are (SF?) and make the hassle of arranging everything, following through with reminders, a facebook event, buying most of the needed supplies, making sure everyone has transportation, etc. Event arranging is a pain in the ass, but if you do it a few times, someone is bound to reciprocate. If you don't work with people anywhere near your age, or you don't care to hang with them after work, then your current job is not socially fulfilling and you should leave.
