One home feed, and notifications built for a social product

The home screen had been a set of disconnected lists, each holding one kind of thing, none of them aware of the others. It is now one ranked feed across posts, notes and polls — which is what the product actually is, and which means a note somebody shared this morning can appear next to the question it answers.

Notifications were rebuilt to match. There are filters, so a person who wants to see replies but not follows can. There are mute preferences that are actually respected. Repeated notifications collapse rather than filling the screen with fourteen separate lines saying somebody liked something, and bulk actions exist so clearing them is one gesture rather than a scroll.

Likes moved to being identity-based across discussions, suggestions and questions. Previously a like was a counter that could be incremented, which is exactly as reliable as it sounds; it is now a record of who, so it toggles correctly and cannot be inflated by tapping.

Counters and ratings on notes became server-owned in the same release, for the same reason: a count the client can set is a count that will eventually be wrong.
