I would say that most folks just listen unless they have a specific problem. Plus there are plenty of folks on there that seem to like to hear their own voices. LOL I like to tune in, but I usually have other things that I can do when the conversations head off to a topic I have no interest in. In my case I have two monitors on my desktop, one tuned to Zoom and the other tuned to whatever else I need to work on. I have also gotten good assistance by asking for help on a specific problem and also learned a bunch by just listening.
