When I took on the co-moderation role for the Buy Nothing Somerville community, there were about 650 members. Now, there are well over 1,400. Unfortunately, I haven’t done a great job nurturing the community. Buy Nothing facilitates the free exchange of goods and service, yes, but it stresses building relationships with neighbors. It’s not just about the transactions. That’s hard to do when half your community is brand new. Today, I began to rectify that with the first in a series of posts, giving “pro tips” on norms for the community that are designed to facilitate relationship-building. I actually wrote a series of pro tips, and I’ll post them perhaps weekly.
