I would just like to chime in to say that users expect links in webpages and not in apps. I fully expect the webpage of hacker news to behave the way you describe, because it's a webpage.

I recently used the best webapp I've ever used - LucidCharts. That was an app, and, as such, I didn't have the expectation that everything I did generated a new link, or that I could even link to certain things. BUT, they also struck the balance of providing web behaviors for things where I expected them.
