But who owns then the #stem tag?
No one owns any tag.
STEMGeeks listens to #stem, #science, #technology, #engineering, #math, and the meta tag #stemgeeks and index them into the tribe but no one owns any of those tags, not even STEMGeeks.
And both tribes use the same token?
I don't believe they have a token.
STEMGeeks is the only distribution for STEM token. I believe StemSocial is a community but not a tribe.
OK, many thanks!
