Now it seems obvious and not worthy of a label, but at least at the time I guess it kinda captured the imagination and people imagined new/different ways to do things (I think it also coincided with a lot better tooling and tech around javascript).
Perhaps web3 will do the same, but so far it just feels like "it's the web as you know it, but now you need to also buy some bitcoin to use it"
However, web3 has nothing to do with Bitcoin which does not provide smart contracts or wallets connected with web apps. Most decentralised apps are built with the Ethereum code (either using the original chain or one of the many forks).
I keep hearing that, but that's been the thrust of the web from well before the term "web 2" ever left anyone's lips.
Web3 was data. The money/asset/whatever was still going through classical channels.
This is happening again now with the web3 fad. A new generation of gullible idiots and sociopaths to take them for a ride.
This distinction only matters with centralized platform like AOL, Medium or Facebook though. Wikis existed long before big companies hijacked the web.
It wasn't user generated. User in this case being the visitor to a website and not its creator.
