I visit a few forums. Most of them are either marketing offers or general chat. The recent discussion I saw on a very famous tech forum is about Disney +
While streaming can be considered a techy subject, I don't know what a tech forum has to talk about it as the main topic. That was the only thread that was moving in the last 2 hours.
Why do you think such a behaviour is happening ?
I will put the blame on the team. If the team takes the first step towards technical conversations, that is what will happen. Also, a bit of general chat is not bad either. But it need not be about personal details or problems.
