Hello,
Thanks for compiling this report − very interesting!
I am curious about the retention of events. How is the number of developers attracted (eg for the Wikimedia Hackathon, 37) computed? Is that based on the registration survey? (For comparison, the report of that event mentions 56 newcomers)
From there, the 3 retained is based on a Kibana query.
- the query only contains 19 usernames. I guess it is because we don’t have the usernames of the 18 others?
- the query appears to look through Gerrit data ; is that a deliberate choice? I would have thought that contribution to any Technical space would count as retained − the same query against Maniphest appears to return 5 users.
