With the recent release of the new profile, we received the impact stat.
It would be really cool to see all users listed by impact. Example:
Add an impact tab to the Users page, and sort users by the approximate number of people reached during the given time frame. Although, it might not make sense to allow viewing impact by any time frame other than "all", as views are only counted, not recorded as time-based events.
Note: for reference, this post requests the data be made available in SEDE.
