I think the idea is great but we already have a Stem community, if this is no cooperation...then how far will there be cooperation? Let's be clear a tag does not make an article scientific or good researched. Communities like steemStem need authors. So will it be possible to use both tags and how will this affect the curation? (@lemouth, @stemgeeks)
If your really scientific you should both know that community splits harm a network. If you end up with two small subnetworks you have possibly quartered the value of the current STEM community on Steem. We are at a vulnerable state where we need union more than ever. Tribes are great if you are a hundred million MAU network, Steemit so far has about 3000 daily active users and 17k MAU, let's keep them a community.
