Awesome tool and as someone who typically spends hours writing a post I love anything that helps good quality content get the recognition it deserves!
I completely agree that comments may be a good way to help surface undervalued posts. Particularly looking at the level of nesting in the comments I think can help determine a post that triggers a good discussion as compared to a post that has lots of top level "great post!" comments.
It's nice to have someone agree with my point of view, thanks for reading.....
By the way I checked out your steem bot tracker project and it was really great, I'd definitely be trying it out in my future posts.... You rock
