You spoke my heart inside out. I also feel that there is something we need to do so that people start to feel sense of belonging on TT.
What I have learned from my community engagement work is that DEEP LISTENING to other person works. In deep listening you are trying to appreciate the other person by reflect his/her own feelings and thoughts. Psychologically, it gives the other person idea that the person listening had actually heard what they had to say and feel validated. This creates a space for both listener and the one who is the speaker. This is the first step perhaps. I found few friends from TT just because of deep listening. It is like you tune into the other. Some people do it naturally, others need to practice it and develop it like a skill. I read once in a book on community engagement a facilitator asked a community worker "are you are radio or a recorder?" and the person said earlier I used to be a radio with people, always projecting what I had to say to the people and never listening to what they had to say to me. But now I am a recorder, I listen to people's concerns and try to BE with them.
I subscribe to an approach to community engagement which is based on the principles of appreciative inequiry and using people's strength to create sense of belonging. I am a member of the organization who discovered this approach in context of HIV/AIDS. Here is an overview of the approach https://www.communitylifecompetence.org/our-approach.html . How can we do that in on an online platform must be a challenge. But I think it would be worthwhile to experiment.
Thanks for bringing this issue up.
