Hi, I can't speak for SteemSTEM but will pass on your query to them. I would guess Linux counts as part of STEM learning. Have you done such articles before that you can link me for reference?

Don't feel too bad, you seem to have received a vote from OCD curators 25 days ago that took your post to $30, my suggestion to you is give commenting a go, support content of others with meaningful discussion on their posts, you may get some votes for writing a few meaningful sentences. Yes by all means try write some linux tutorials on Steemstem, also try interfaces like https://palnet.io also we need some people to bring https://bitsports.io forum to life with short commentary, I vote those myself with 50 to 80 cents for just engaging in short-form sports banter.
