Hi @maticpecovnik,
Fantastic, StemQ biggest need right now is for knowledgeable contributors to answer questions.
But StemQ also promotes contributors to post articles about specific subjects in the form of a question and an answer.
So yes, feel free to submit future STEM posts as a question post + answer post.
You just need to leave 5 minutes gap between both posts as Steem won't let you post 2 blogs consecutively.
For now the StemQ is quite basic so questions are not "directed" to users.
You can check the questions for a particular subject by going to the "Topics" page.
Feel free to ask me for more help here or on the Discord server.
Happy to provide any assistance required.
Cheers,
@irelandscape
