Learners stats: a proposal.
Hello, it would be nice to have a second data in the courses page, besides learners number: active learners. It could be measured as people with at least one-day streak, this way anyone would be able to see the "active community". One issue is that this wouldn't count people learning that very language, but still...
Or it could be measured as users active in that language last month (or the last three months). Not everyone tries to maintain a streak, so this longer time period would include people who might only use Duolingo a couple of times a week or those who are on holiday. It could probably be implemented as a running count of users so continuous stats would be available. Of course it is possible that Duollingo already has this data, and has not yet chosen to make it accessible.
