@Deborah0, finding your post now, 2 weeks after you posted it - whom could Marjo have hailed to the rescue?
It's an interesting question and maybe the reason for the way this group looks.
Before I fell into Anectodes and Stories this Summer, I knew tech forums, where you post a question or find a thread of someone else with the question, find an answer and go or don't find an answer and may dutifully come back to give the answer when you puzzzled out the solution yourself weeks or months later. That's not really a group, it's unconnected people with questions and anwsers and everyone sticks to the topic as there is no reason to do something else. If you hunt for a way to connect an old printer to a new computer, you won't linger and chat about dishwashers.
In Anectodes, sometimes I told a story and there where a few comments, a few likes and that's it. And then there are questions or an ongoing situation for someone and the discussion spreads out into discussions, subdiscussions and at the end there are lots of subdiscussions and someone drops in, reads it all and states at the end, that that is hilarious and makes another comment and starts it all over. It's like a party with talks here and there, someone goes for a drink, someone for a dance, they come back and go on, sometimes people posting a short remark from their phone at work or from bed at 2:30 am.
Over all the thread, conversation goes back to the topic several times, problems get solved, people get help who did not even know they needed it - either in advice, either by laughing so hard they forget their worries or even their depression.
That's a group, that's why I participate.
And I really don't think that that is a thing can be improved by being under staff surveillance. The way these new groups are organized, under surveillance, no subdiscussions possible, it's transforming groups into tech forums.
