Shortly after sending I realized that it's exponential, not quadratic (which was the initial idea), sorry for the mixup.

I'm not sure whether I can follow. Do you mean for 

1. currently active contributors who have been active in the past
2. currently active contributors who have not been active in the past
3. for both equally?

If you mean that it's equal for all in (1), that would be just like intended as the goal would be to give them more voting power than those in (2).
It would also give those a vote who have contributed in the past but are no longer active, yet decreasing over time.

I'm not sure how it was done in the case you are referring to, but it sounds like the time axis there would have been scaled  to the begin of their activity, while in this case, it would be absolute.

(please correct me if I'm misinterpreting)

Also, in the academic area, one usually doesn't stop activity like it happens in case of ffmpeg, for which one would be given decreasing weight of votes over time.


I'm not actually proposing this as a model, but some had said that contributions from past times (earlier than the 3-yr GA range) should give them more weight in voting, and my answer to that is, if this would be done, then it should be at least in a way that recent contributions will count more than older contributions.

What was the outcome in the academic world - back to citation count?
