If your platform doesn't make it slightly hard to speak, it will be full of noise
This is partly a defence of InsightNest's own design, so take it with appropriate scepticism. We require a 50-word minimum to post a Contribution. We require you to have read the Spark for a minimum time before the form unlocks. These feel like obstacles, and early users flag them as such. But I think the right frame is not "barrier" but "signal cost." The friction is the mechanism by which the platform communicates what it values. A platform that accepts one-word responses is a platform that values volume. A platform that requires minimum reading time before response is a platform that values having read the thing you're responding to. These are product values expressed as constraints.
