We want to know to what extent newly registered users interact with Echo notifications. Knowing that can give us an indication of how interested we are in also knowing more about the extent to which new users get notifications. This leads us to posing the following question:

• What proportion of non-autocreated accounts interact with Echo notifications in the first 24 hours after registration?

If the answer is "a substantial amount", then we might want to ask these follow-up questions:

1. What proportion of non-autocreated accounts receive a notification in the first 24 hours after registration?
2. What kind of notifications do they receive?
