> For a few weeks, I am doubting if HN is another "user engagement" place like you know Reddit, FB etc.
If you cannot engage an audience, people don't crowd around to hear you.
HN is a place where people come to showcase what they create, share something that good hackers would find interesting, and comment on others' submissions.
As you may know, visitors to the site are wide-ranging in background and interests. Here I would restrict my reading to what suits my tastes since I am not a polymath and comment on topics which I am knowledgeable or want to learn more about.
