This task is about analyzing how people are engaging with the Topic Subscription feature while it's been made available as an opt-out preference at a sub-set of wikis to help us determine whether it is ready to be made available as an opt-out preference at more wikis.
=== Analysis timing
Q2FY2021-2022
=== Purpose
**Purpose**
- Learn whether Junior Contributors are able to use Topic Subscriptions successfully.
- Learn whether Topic Subscriptions are negatively affecting other volunteers' experiences.
**Decision(s) to be made**
- Decide whether any changes need to be made to the notification interventions before measuring the impact they have on peoples' likelihood to receive more timely responses to the things they say on Wikipedia talk pages.
**Research questions**
1. Are Junior and Senior Contributors able to use manual topic subscriptions successfully?
2. Are Junior and Senior Contributors finding topic subscriptions valuable?
3. Are Topic Subscriptions negatively impacting peoples' engagement with talk pages? //E.g. are we seeing a sudden increase in the percentage of new comments that are reverted within 48 hours of being posted? Are we seeing a sudden increase in the percentage of people who are blocked after posting a new comment on a talk page? Are we seeing a sudden decrease in the percentage of notification that people do NOT open, by type?//
To help answer the questions above, we would like to understand the "Engagement metrics" listed below.
