Injured horse or new stackoverflow for all.

Hi, Indiehackers!
My name is Yevhen, I am from Ukraine.
At the beginning of autumn I made the decision to become an indie hacker (then I didn’t know what it was called yet :-) ) In a couple of months in my spare time I made a small MVP. And I'm looking for feedback from the first users.

About the project.
People are constantly looking for answers to their questions - on various Internet resources (Facebook, YouTube, Twitter, Google, etc.).
I want to create a platform where people can share their expertise and knowledge on various topics.
I wanted it to be a resource where people would find answers to their questions, give advice, and monetize their knowledge. One place where everyone can find the information they need from a trusted source.

For this programmers already have - Stackoverflow.

At the moment, I'm trying to attract the first users and test the idea.

I would be grateful for any feedback, advice, criticism, recommendations.

You can try to create any test accounts and questions / answers on the test subdomain - https://dev.brren.com

Every day I write several messages to people from social networks who have followers. And who give paid consultations to their followers. But so far nothing comes out. I want to understand - the idea is bad and dead? or am I just not promoting it correctly?

If it's really bad, please help me to shoot this injured horse :-)

p.s. Maybe my terrible English is to blame?
