There is (well, was) a questionnaire for new members, which we have the database for. I had a look at that, but the questions don't seem to aim to do more than market research. No way of identifying sign-ups with subscriptions.
I think we should probably check the trends of subscriptions, and their renewals.
However, a search for other evans finds @evanburchard, who might be the same user?
Anyway, I'll send an email to both users to ask if they don't reply here.
social.coop is a a coop-run corner of the fediverse, a cooperative and transparent approach to operating a social platform. We are currently closed to new memberships while we improve our internal processes and policies, and plan to re-open to new folks when that work is complete. [9/2/2018]
