I think it&#x27;s less about promotion and more about feedback. &quot;Here&#x27;s what I&#x27;ve built, what do you think?&quot;<p>We&#x27;re meant to be an inclusive community of smart people. The idea is we&#x27;ll encourage the poster and offer constructive criticism (or praise).<p>If the post is useful to no one, it simply won&#x27;t get discussed or upvoted. When something does, it&#x27;s validated as an idea, or as something of interest.
