> My personal preference would be a network recommendation system. I would like to know what people I know (and in my extended network) are using and like - being it restaurants, clothes or open source software. I have 90% of friends (or friends of friends) satisfied with something - maybe I should try. Of course it is not a perfect system, but seems much better than what we currently have...

I can think of a hacky solution where your friends can share their (trustpilot?) or alternative accounts username and then you can review what they are reviewing/what they are using etc.

The problem to me feels like nobody I know writes a trustpilot review unless its really bad or really good (I dont know too much about reviewing business)

I feel like someone must have built this though

Another part is how would you get your friends list? If its an open protocol like fediverse, this might have genuine value but you would still need to bootstrap your friends connecting you in fediverse and the whole process.

And oh, insta and other large big tech where your friends already are wont do this because they precisely make money from selling you to ads. It would be harmful to their literal core.
