Web 3.0 has been used for a long time to mean any P2P/distributed/... approach, not just blockchain, even if the blockchain people try to completely take over the term sometimes.
Reader view, tools for the visually impaired, and browser automation are actually useful and commonly used, so that definition win the title for me.
There are certainly useful distributed web tools (e.g. email, TOR, IRC, Matrix, self-hosting, bittorrent), but they're the opposite of recent trends towards monopoly.
The distributed meaning is absolutely poisoned by blockchain at this point.
