The front ends could probably do a better job at giving visibility to content based on different metrics. For the time being the current reward pool model is "good enough" as a coin distribution mechanism. We could do better. If the coin had a wider distribution the curation built into the system would be a close indicator of the popularity of content but it is waht it is I guess.

How difficult could it be to come up with a front end that you can customize to show posts by shares, comments, views and payout? Why do we keep using the same model?
