I know it's frustrating to write content and see no engagement. Here's how I am trying to change that:
1. Start posting on Twitter. I have rarely used Twitter, but I decided to post my medium articles with proper hashtags on Twitter and I see some engagement from there. Even if it's just one or two people. And since you write Tech content, maybe it can help. And Quora, you can start answering questions and adding your blog links. I am trying these two things as well.
2. I read somewhere on Medium itself that don't worry unless you have written 100 blogs for yourself. So, I am trying to work on that.
Hope it helps!
