I am a developer, and recently I have chosen a niche that interests me. I have went to people's websites within this niche and emailed them something like the following:
My name is Mark Mullins and I am a software engineer. I am doing research on <niche> software and I wanted to reach out to ask you a few questions.
However I have not received responses. I don't personally know people within the niche. How do people go about finding problems that people are having within a niche?
