This is a lovely suggestion. Upvoting for transparency. And yes, ranking of dozens of dApps will be different. I do remember, back in those days, Steemit was ranking really high. Not sure how or why.
It also has to do with the technical aspect - and not merely onsite optimization. Again, like you said, to get all the dApp devs together and get them to discuss would be perfect to bump up the rankings.
And then, with time, we can monitor and see what's next.
