The #steemstem tag is the tag which goes along with the @steemstem project. I am glad that you find that the content submitted to that tag is of a higher quality then other science related tags. We are working hard to build this community, and support authors who are putting in the efforts to produce interesting content, while maintaining good citation/crediting practices. I am quite proud of the progress we have made, and the posters are some bright and kind people. Thank you for your efforts to further spread the word on the wonderful work these posters are doing.
