This is a pretty good idea. This kind of data is a little less distorted and easier to interpret than the information we get by seeing which posts get to the front page, have the most upvotes, earn the most money, and so on.
Hopefully a big fat whale comes swimming by and gives it a nudge. The sample size is critically important to having meaningful results. And it looks like we are only seeing 1 response for every 4 upvotes. That alone might be a point of analysis...
