Please join us on the steemstem chat.
Honestly, I do not think flagging is the best way to educate people, which is what we are trying to do in sharing good stem content. Taking my own personal case, I am always happy to see someone outside my field talking about my field. Even if there are errors. It will be my pleasure to correct and explain. This will give better results than a flag, IMO.
But let's discuss that lively on the chat.
EDIT: and welcome to steemit! :)
