I am struggling to understand. Why is a social-origin visitor more valuable?

Honest question. I would have expected an RSS-origin to be a more tech-savvy reader and more likely to engage.

Engage where? Engage how? Tech savvy may not be what you're looking for, and is not always a good thing.

I think what fulldecent is saying is that people reading on RSS have a barrier to sharing and a barrier to commenting that doesn't exist on social media. On Twitter or Facebook, the "share" action is intrinsically linked to the article in its native format. Not so on RSS.
