The Best Websites (2020 Edition)

I know, I know, such a vague title. But first let me explain what I mean by “best” websites. The websites that if tomorrow they went down, someone would miss them, someone would have troubles. “public goods” 

Example: If Facebook closed tomorrow, there will be chaos in Wall street, lots of people would complain, no more lolcats and far-right posts but after some time everything would be back to normal. Users would move to other social media websites and life would continue.
