"You just described a subscription service", nope I think the defining character of web3 is a decentralised and hopefully anonymous community, driven and voted for by a blockchain powered mechanisme with a transparent, verifiable chain of decisions. In my opinion this is quite difficult to achieve with conventional organisational structures.
I run a house sitting site where house owners post listings for house sitters to respond to. Sometimes I flirt with the idea of making this community a decentralized autonomous web3 community. Currently I am the sole arbiter and mediator when there is conflict. I would love to shift this responsibility to a random selection of active members that have enrolled for this role for a certain time period. I envision a rotating council formulates the complaint, and a selected group votes on a set predefined outcomes. Members pay a virtual crypto currency and when problems arise this fund can be used to pay for insurance claims. Still very much in its infancy but I could see a good use case for web3 here.
