Blogging platform for software developers that people read but no sign ups. Am I doing something wrong?

Hi to all. First of all, I hope you are all well and healthy in these pandemic times.

I created a blogging platform specifically created for software developers. You can check what features there are on https://therebelsource.com/about because I don't want to make this message too big.

My biggest challenge is to make other software developers use it and create blog posts. I created two posts so I could attract users but people only read the post and then just leave the app. They don't stay to register.

Can anyone tell me am I doing something wrong or is it just a slow process?

Thank you.
