Hello @bhoa,
I'm glad you came back in 2020. It can be very discouraging if no one votes on your posts. But since I have lived a long time (as my post indicatesš) I think communities are really helpful for establishing connections, and connections are the key on Hive. People have to know you exist before they can vote for you.
Thanks so much for that wonderful comment. I will try to keep up with your stemsocial blogs. They are always interesting.
Regards,
AG
