Venkatesh Rao@vgr·Aug 5, 2020What's a good way to measure churn in a customer base? Like an email list specifically? Feels like it should be something like sqrt((subs+unsubs)²/(subs-unsubs)²)63
Sam Bhagwat@calcsam·Aug 5, 2020Replying to @calcsam and @vgrEg why do you care about churn? Are you measuring it for curiosity? Trying to predict income? Etc1
