Thanks! The most interesting datum I've noticed so far is the rate of active editor (5+ edits/month) retention among new contributors after six months, which is about 0.4%.
Is "active editor retention" a metric defined somewhere? It's not in https://meta.wikimedia.org/wiki/Category:WMF_standardized_editor_classes.

That (along with the easy-to-measure and already known sheer quanities of photos generated) seems to me to be the most robust number to use in evaluating WLM (and comparable) funding requests. 0.4% may be considered worthwhile or not enough, depending on local contexts, so I'm not drawing a universal conclusion from it, just noting it.
