I feel there is an earnest, looking-to-help type that isn't cruising twitter. Also twitter can be so fragmented and search is meh. The 11k group is a top-5 result searching for covid in facebook groups.
In the facebook group: Networking, exchange information, project ideas, showing off things people are making, bemoaning lack of coordination 🤪. Probably it's best suited for feeding the slack groups tbh. Facebook groups are 🗑️ for threading.
