The problem with this "web 3.0" proposal is that the tech is web 2.0. RSS, diaspora, pump.io and friendica have all been around for ages. The real problem is a lack of incentives for those in power (generally those with large marketing departments) to adopt or support them. We see this every time a major service slowly kills off their API. Data portability and interoperability are nice for gaining adoption, but the first thing you kill when it outlives its usefulness to the centralized entity. And the average user doesn't care about this, and probably also doesn't want to do the research to understand decentralized federation. People already unlearned that gmail is distrinct from email, and here we ask them to yet again anchor their trust in even smaller entities than your average email provider to curate their social feed and keep their instance up. It is a much better vision of the future of the internet than web3 - even through web3 sells the blockchain as the magic silver bullet to these issues. But it will fail for the same reason.
