@design_RG I think the key point there I agree with is the nature of the crowd formed. As long as everyone who joins is explicitly a STEM enthusiast as a central point of interest for them, that is enough.
But I see a lot of people who come here who have never made a single STEM related post and doesnt seem to comment much on STEM related topics. That's an issue.
To me if your bio lists a few STEM related interests, profression, or study that would be enough for me to say someone is a fit for the community.
