Web 2.0 and 3.0 are not directly comparable just because they have similar names, a fallacy of equivocation.
Web2.0 might have had a silly name, but the idea of the web as something that the average user and company could contribute back to and use to communicate with in real time
provided explicit value and convenience over existing alternatives (letter writing, door-to-door sales, in-person self-promotion, calling a pizza parlor, renting a physical video, long distance phone calls, physical plane tickets mailed to your house…)
I don’t see that with web3.0.
