@bob @u2764 On the !GNUSocial side, subbing to Groups and Tags helps bring people of similar interests together. We have groups for languages, sports, politics, foods and beverages, geographical area, programming tools, health & diet, and more. The !fediverse is full of regular people as well as more technical folks. But new arrivals, as is true anywhere, have to take the initiative to find out where and how to connect to others that share their preferred interests.
