I think you're very right. Most people here ask questions in which they already know the answers. Maybe they're trying to see if others will get the answer or they're doing it just to stay active and get support from musing. Though I don't think there's much fun in asking what you already know the answer to.
I believe so too. That's why I ignore most of the questions related to steemit or crypto here. Most questions about steemit most people ask here are questions they already know the answers to and it's not helping the platform. That is why I love answering questions here where the questioners ask for people's opinions, not questions with direct answers or answers that can easily be found on the web.
