We'll want to talk about what types of metrics might give us information about if this feature is successful or not (or worth spending more time developing.) Some of this might already be queryable, but we'll need to list the questions we want to answer first, then decide how to get the data.
**Questions we'll want to answer with data**
// This is just a laundry list, we'll need to refine it.//

We'll need to stick to the Privacy by Design Policy and Ryan Kaldari may need to walk us through any privacy landmines.
