I am not a statistician, but I think something that needs to be taken into account when considering the numbers that you have presented, is that the more time that passes, between when a post is made and the present, the more likely it is that a:

• post will be voted on; and
• question will be answered

This is because the more times a post is viewed, the more likely it is that 1 to many people will take an action on it.

Of the four sets of statistics that you have presented, I think only the second one will not be heavily correlated with time since posting.

Another observation that may or may not add value to this discussion is some manual copying of data that I did from https://stackexchange.com/sites#oldest. It is a table with data from the 11 sites that launched 9 years 7 months ago (of which we are one). On most measures we seem to be in about the middle of an illustrious field.

Another observation that may or may not add value to this discussion is some manual copying of data that I did on 20 Feb 2020 from https://stackexchange.com/sites#oldest. It is a table with data from the 11 sites that launched 9 years 7 months ago (of which we are one). On most measures we seem to be in about the middle of an illustrious field.

On 10 Mar 2021, I re-ran the analysis above with data from the 11 sites that launched 10 years 8 months ago (of which we are one). On most measures we seem to be in about the middle of an illustrious field, and on all measures our ranking is the same as last year.
