What is an insightful comment worth if nobody reads it?

If a tree falls in a forest, and nobody is there to hear it, does it make a noise?

I remember, maybe about a decade ago, being annoyed that Facebook had begun showing my comments in other people's timelines. Eventually, I got used to it but as an introvert, I never understood why they did that. Perhaps, until now:

Here on Steem, as I already noted:

(Feed-Reach is zero for comments and replies)

The consequence of this is that comments and replies have a near-zero chance of being seen by more than a few participants in a conversation. The reverse of that is that the cost per feed for comments and replies can be seen as infinity.

It's an obvious point, but maybe not insignificant? Simply put, maybe it's the case that storing comments and replies with near-zero reach in a social media platform is expensive and inefficient?

Coincidentally, I already started to address this point with the Steem Conversation Accelerator (SCA), but as a result of the new "feed-reach" metrics, I'm thinking that maybe it's more important for the blockchain than I had realized?

What do you think? Should developers prioritize efforts that could bring "reach" to comments and replies?
