Sorry, I'm late. I think you should go on with the SteemSTEM tag because it is a really good community and also supportive. The nature tag is so broad just like you said, better stick to the steemstem tag.
Actually, I also have a visibility problem like other newbies. So, I want to help other and vice versa.
Thanks for helping give visibility to those of us that have a harder time navigating the waters!
Thanks for reading my post. I will send the reward now.
