The beginning
Old bookmarks get buried
Twitter's Bookmarks let you save tweets privately and come back to them later. But everything you saved ended up in one long list, newest first, with no search. So the more you bookmarked, the harder it got to find anything older.
I ran into it myself all the time, and when I asked my mutuals, they said the same thing: the only way back to an old bookmark was scrolling, and most of the time they couldn't be bothered. So I took it on as a self-initiated project, from research through to a high-fidelity prototype.
