I tried to make a way of sharing posts with friends without having to be on a social network... I came up with NoteSub:

I like it. And mass adaption is not required to use it.
I would have loved to have made this a true social network in some regards, however, there are issues of moderation and storage that become very expensive at scale.
Moreover, adoption of a new social network is super hard to promote. So many Twitter, Insta, etc clones have failed because they are just 'clones'. Not offering any thing new.
It should be considered although Thiel talks of 0 to 1... A great deal of dramatic software/hardware progression comes from a highly evolved successor to an average pre-existing product.
The iPhone was not a zero to one, nor was Apples GUI, they were just highly evolved versions of average or below average products that already existed. Social media apps are already highly evolved for their function. We need something better for edge cases, but the current state of social media platforms means that something supremely better is required before any adoption drive becomes meaningful. When such a product comes, mass adoption is inevitable; we crave and succumb to better ways of communication and contact.
I don't understand what it has to do with sharing, it just seems to be a note-taking app? It even talks about being local, offline and can't even sync with your own devices unless you pay.
But nothing obvious about your friends being able to see them.
You make a note, they are designed to look as good as any social media posts.
You can share the note with whomever you wish, using what ever messaging system you you like, and the note will look as good as a social media post, ie how you designed the note. I am sorry, it does take a bit of imagination. I never wanted to pitch it as a social media app, but, its as close to personally controlled social sharing that I could conceive.
You dont have to pay to use it. Very few people need to use cross device sync and those who do seem happy to pay for it.
Ie, it is free, so if any ones wants to try it, I would love to hear.
