I had a dream that I was on a space station, and our old van was a shuttle. An escape pod failed as we were leaving the station, and my dream went into orbital mechanics ala Kerbal Space Program. On waking, I pondered orbital mechanics, and realized it’s just like people.
Community is like orbital space. Each person is a satellite. Your interests, drives, life and death all define your orbit. Your location is the barycenter of your orbit, the focus of your ellipse.
Along your path, you will pass near other satellites, people. If your orbits are not close, it may be a single encounter. Maybe your orbit lines up repeatedly. Maybe not. Communication tech is better mowadays, and you can talk to someone orbiting Jupiter with a little lag.
But, you only have so much fuel (drive) to change your orbit. And if you aim for someone not on on a very similar path, you almost certainly guarantee that your paths will diverge more widely.
Unless you grab on and become one peice in a new, combined orbit, a risky maneuver. Instead, it’s less disruptive to adjust your orbit on each pass. Move your center when you can, and look for other satellites near you.  
Which satellites seem familiar. Is there a shared mission or purpose. Can you benefit? Are they from a friendly nation, or do you need to be on guard? If they are new and suddenly there, are they a risk for knocking you out of your planned orbit, or dragging you down the gravity well? If you join up, they be too big of a mass or too tightly coupled for you to change your orbit later? Or are they a whole new anchor in space to orbit freely, yet still taking you for a ride?
The best are when you orbit the others who orbit you, or you share closely overlapping orbits. If inclination matches, you meet more often than every orbit.
I have lots of acquaintances in unmatched orbits. *waves*
I have several friends in harmonic matched orbits. Hi Hi Hi Hi Good to see you again.
I have a few people that I try to keep my orbit matched with. I definitely have my own mass and velocity that makes this difficult sometimes, but I appreciate those on similar missions burning their limited fuel to help us stay in sync.
