Thanks for the feedback! Sometimes I wonder how many people are reading, so I really appreciate it.

I am pretty sure that answering "not many" would be quite correct... Unfortunately, I think that most STEM authors are in this situation. However, how to better attract content producers otherwise than by providing good content to read?

This being said, I have read your post. So at least the number of reader is greater than 0 ;)

Is it appropriate to use the #steemstem category for these? I only included it on this post because I incorporated steemstem content, but otherwise I've been avoiding the tag because I thought it was reserved for primary material. I'll certainly add it to future science & technology posts if this series fits there.

The content discusses STEM. So yes: feel free to use the #steemstem tag (I would even encourage you to do so).
