The internet, somewhat ironically, really needs a search engine that works in the current day. You can't find anything anymore. It's like Google has been un-invented. Hopefully some day soon the internet will be searchable again. Thanks to everyone involved in attempting to make this happen (preferably in a non-profit-maximized way).

I have a feeling that people stopped writing actual good website content for certain topics and moved to places like youtube instead. Youtube frankly offers better monetisation and most importantly easier user retention via subscriptions.
I tend to think the quality of the content tends to be better when people don't think about stuff like user retention or subscriptions, but rather how it will actually reach people that care. Good search/curation is a key component for that.
Of course such a world free of implicit monetization will require it to be explicit (Patreon-style), but that should massively realign incentives.
