The worst part is, this model would incentivize clickbait even more.

This is precisely the problem. I subscribed to some sort of a pay-per-article newspaper site some time ago, and the idea of paying 8-17c per article made me fear committing to reading anything. I ended up dropping it.

Really, "micro" payments are not micro at all! "Micro" should mean a thousandth of a dollar at most, with the assumption that volume will make up for the profit.

Definitely. No one would read replies to their own comments either, because they would have to pay back the money they earned when their interlocuter read their comment.
