What the source says
How to interpret the signal
The public model includes reply-related predictions, but that does not make every reply beneficial. Eligibility, viewer relevance, the state of the conversation, and negative outcomes still apply. Reply volume is an action count, not evidence of useful discovery.
A practical example
A reply to a mid-sized specialist can be strategically stronger than a generic comment under a celebrity post. The smaller conversation may offer better audience overlap, more room for a distinct contribution, and a realistic chance of continued dialogue.
Action for builders
Reply when the topic is relevant, the conversation is still active, and you can add evidence, context, a concrete example, respectful disagreement, or a precise question. Skip when only generic praise is available.
