I'm wondering if anyone knows of any research on Wikimedia meetups and the effects on editor retention?
Sincerely, Laura Hale
I know that at some point there was effort made in the WMF's Global Development department to try and track any statistically significant increase in participation from certain geographies as a result of outreach events, but I am not sure how far it got.
Making a correlation between IRL meetings and activity is difficult unless you do it by hand. And then there's the question of what you might use as a control group as a basis for comparison.
