Sure, but I suspect also harder because it's full of contrarians that will point out at least five better ways of solving the problem and people that upon being greeted with anything that looks like disguised marketing copy will spontaneously combust. And if you do manage to sneak a URL into a discussion without anyone thinking it's marketing, the next four comments will be about whether the design of the landing page is unsuited for people with 2400 pixel wide monitors or people with noscript enabled

(Also it's the kind of website where you absolutely can get good responses from "Show HN: A thing you might want to use and here's how much profit I'm making from it already" until a bunch of green usernames say nice things about it)

Contrarianism is an effective sockpuppet tactic, then, in order to buy legitimacy and trust in the marketplace of ideas.

But also easier because those comments quickly become dead.

Its a goldmine for social engineering, has come in handy personally a few times.
