An attempt to stay relevant by piggybacking on the historical success of the web 2.0 brand, pushed by those personally invested in crypto, but who are totally not pushing this for their own profit. Or, less sarcastically, it's a collection of technologies that attempt to link the blockchain with the "real world", supposedly bringing back decentralization to the web in the process. I'd like to elaborate but there's really nothing more to elaborate on, the entire thing is a vague collection of ideas (such as "maybe users could use blockchain-based microtransactions to pay for the sites they use instead of being served adverts") that nobody's actually figured out what to do with. Why exactly blockchain is required for these ideas, or exactly what ideas constitute "web 3.0" is still an unanswered question...
