What are the consequences of this? Would it provide any value? My guess is that user's would be more likely to answer questions rather than ask them if some form of reputation were involved as well.
If you search thru meta for "ratio" you'll find various Q&A and proposals around all kinds of ratios. The consensus is that they all kind of don't do what ppl want and just become a distraction.
- Should we have a policy about "too much downvoting"?
- Healthy ratios for asking:answering and up:down voting
- Add a question/answer ratio below the % accepted stats on questions for the asker
I can go on but basically from what I've seen around this is that ratios can be found out using the SEDE if you're really interested in finding out things like this but in general the opinion of Jeff Atwood and Joel Spolsky and others have come to the conclusion that ratios don't really offer anything positive to the site.
This was part of the reason that they removed the ratio of accepted answers from the UI a few years ago as case in point.
That last link is the proposal to remove the accepted answer ratio BTW.
