About

PG has posted about improving social networks using something like an &quot;intellectual CAPTCHA&quot; many times [1][2][3][4] - &quot;Make users pass a test on basic concepts like the distinction between necessary and sufficient conditions before they can tweet.&quot;<p>I felt the same way. So I built one using a mix of simple math, logic, and Twitter&#x2F;X Community Noted posts. Try sample questions here - <a href="https:&#x2F;&#x2F;mentwire.com&#x2F;sample" rel="nofollow">https:&#x2F;&#x2F;mentwire.com&#x2F;sample</a> - without signing up.<p>- Invites are temporarily open to HN users.<p>- Onboarding test + one daily question before accessing feed, post or reply.<p>- Posts authors are anonymous until upvoted or downvoted, forcing evaluation of content on merit.<p>- Face ID (on-device only) to post&#x2F;reply, pangram checks for AI text.<p>Sourcing good questions turned out to be much harder than I thought. If you have suggestions to scale this, I would love to hear. Eventually, could be gated across disciplines&#x2F;topics to get a competence × interest graph instead of the pure interest graph of today&#x27;s social networks.<p>[1] <a href="https:&#x2F;&#x2F;x.com&#x2F;paulg&#x2F;status&#x2F;1235949761359904768" rel="nofollow">https:&#x2F;&#x2F;x.com&#x2F;paulg&#x2F;status&#x2F;1235949761359904768</a> [2] <a href="https:&#x2F;&#x2F;x.com&#x2F;paulg&#x2F;status&#x2F;1576517990182359040" rel="nofollow">https:&#x2F;&#x2F;x.com&#x2F;paulg&#x2F;status&#x2F;1576517990182359040</a> [3] <a href="https:&#x2F;&#x2F;x.com&#x2F;paulg&#x2F;status&#x2F;1514979883948126209" rel="nofollow">https:&#x2F;&#x2F;x.com&#x2F;paulg&#x2F;status&#x2F;1514979883948126209</a> [4] <a href="https:&#x2F;&#x2F;x.com&#x2F;paulg&#x2F;status&#x2F;1505842647319126016" rel="nofollow">https:&#x2F;&#x2F;x.com&#x2F;paulg&#x2F;status&#x2F;1505842647319126016</a><p>Repost from <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=47577829">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=47577829</a>.<p>This link contains a full quiz and linked directly to sample to try without signing up.

AI Score Reasoning

The project addresses a valid pain point in digital discourse quality but faces extreme friction-to-growth trade-offs that typically hinder venture-scale social networks. While the 'intellectual gatekeeping' creates a high-signal niche, the difficulty in scaling content and the inherent limitation on TAM make it a challenging investment.
