Maybe there can be some kinda suggestion box and a voting system for suggestions or existing things? Like an open suggestion box, where people could submit potential entries and vote on whether they belong there and are dead or not. And for existing entries, to vote on whether something is truly dead or not, like 'yep, this is dead', or 'nope, this is still alive' (some things may be less popular, but that's not them being dead/actually completely discontinued and defunct). Not necessarily for ranking or putting it together into one score, but perhaps just showing a number of how many people think either way about something
