This topic comes up from time to time but usually buried in something else. I have found that polyamory (or other versions that boil down to having deep, romantic, non-exclusive relationships over time) is the most consistent way to keep anarchist community strong over time. Obviously this isn't everyone's goal. Some people want insurrectionary (sudden, bursting anarchy that can go away as fast as it comes on) relationships. Others want organizational relationships (manifestos, lots of meetings, and hard straight lines).
