## Limitations

-   Measurement (estimation) error
-   Bias...?
    -   Offline versus online populations

    -   Geolocation bias (?)
-   Other applications...?

## Group work

1.  Come up with a question answerable using `get_user_followers()` or `get_user_following()`
2.  Formulate code needed to request that data
3.  (If access granted) make the API call to get data
4.  Consider limitations + design considerations
