What would you like to know or learn about?

I'm brand new to the Steem environment, and actually got led here by JerryBandfield while busy watching some YouTube vids on crypto currency trading.

The problem I have, is that there are sooooo many posts on all kinds of topics but are they answering a need or a question here?
My background is engineering, mostly electronics, electrical, software etc. and have a lot of experience in the industrial and mining sector as well as battery powered electric vehicles.

If there is a specific topic someone would like me to cover or explain, would you please reply to my post with your question?
Hoping to hear from the community soon.
