There isn't a million and one tags, just the ones relevant. STEM, Science, Technology, Engineering, Math, StemGeeks.
As for this post being tagged for STEM, it is talking about STEM content, and as an admin of the community it is very hard to avoid meta discussions. All the rewards on this account are burned though so it is a moot issue.
Meta discussion about stem token and stemgeeks is bound to happen and I'm not opposed to it and it being tagged, it's when hundreds of people do it just to get some STEM tokens I have a problem with it.
RE: Are you publishing STEM content or just shoe-horning to use the STEM tag?
