Based on the title I thought this was a personal call-out to me and others like me who obsessively bookmark/save links and yet seldom even glance at their collection.

This is (tragically) the reason why I remain a tab hoarder: the UI carries an implicit nudge (a costly signal of visual real estate), for my future self to engage with it.

In a similar spirit to OP: it did help mitigate the hoarding, when I began thinking "how hard is it to find this resource/reference again, should I actually need it?". And if it's trivial to google (and mnemonically sticky enough I can trust my future self to remember it), I can close the tab.

same here. That is why i came to discussion to find out how are people using those.
