I don't know about web3, but somehow github is quite similar to what we had in the olden days; just search for 'awesome any-topic' in github search, and you will get a curated list of interesting links on nearly any-topic. Also github pages lets you do your own homepage in a git repository, so it's a bit like geocities ;-) I mean our benevolent owners at microsoft give us a free space for self expression, which isn't a facebook/google style walled garden and targeted add pusher, or medium like subscription extractor. It's even better than geocities, they don't put up any adds at all!
You even have the 'The definitive list of lists (of lists)' https://github.com/jnv/lists - looks like the same old culture that moved over to a new home in the sun. (now this spaceship is very fragile, and might disappear upon any minor change of the EULA on github, matters as usual ;-)
