When we implemented the new notifications menu last year, we originally had likes sort as other notifications do, but got a fair bit of feedback that it was unnecessarily noisy and was causing people to feel like they had to clear them.
We then adjusted that logic with this change:
We want to allow unread likes to sort lower than newer, read notifications on the main tab so that people don’t feel like they must clear these notifications.
So, for the main tab, the sorting algorithm changes from:
- unread with priority in reverse chronological order
- unread without priority in reverse chronological order
- read in reverse chronological order
to:
- unread with priority in reverse chronological order
- unread without priority in reverse chronological order (but exclude likes)
- read (and likes, whether read or not) in reverse chronological order
