There was an idea to make a fully or partially decentralized social network with profiles and a rating system, convenient web3 authorization, a private messenger, where you can also comment or suggest ideas, projects, look for like-minded people and contribute to the crypto community together, conduct Bounty and Airdrop and other activities from the current platform. The last point can be given special attention, making them functionally like Zealy and its analogues.
So that the news feed platform is not empty at first, we can parse popular tweets from crypto Twitter accounts and sort them into categories: Bitcoin, Altcoins, NFT, web3 and others using artificial intelligence tools.
See
gm.xyz, it's on ethereum and does few things you mentioned which are: web3 login, profiles and rating system, private messenger and communities.
There is also
hive.blog, I personally find this project heavily underrated. It does many things already that web3 communities are trying to achieve.
