I think that's likely true for social media apps where the product is "free" in that users are the product and advertisers are the customers that fund it. In that business model, your number one goal is to maximize eyeballs.
But Haven doesn't have that business model at all, so it's not clear to me that a way to control who sees what posts would harm success.
By analogy, farmers want to grow as many plants per acre as they possibly can to maximize revenue. The idea of potting their plants individually makes no sense. But if I just want a plant on my windowsill and don't want dirt everywhere, a pot is what I want.
Any talk of tech people and farmers seems to always change to pot.
Probably the big risk for this thing is that nobody wants to keep track of separate websites for dozens of individuals, most of whom only post something they can see once a week at most. You need to aggregate all of those updates from dozens of people you know into a single website and build a feed, then you have something that probably always has something the user might find interesting, and all in one place, so they'll actually check it regularly.
Instead, have a system where you can categorize your posts and other people can explicitly opt-in or opt-out to following particular categories.
That way, you can do a series of detailed posts on Orson Welles (say) for interested parties without worrying about whether you’ll bore or scare off the rest of your friends.
That seriously pissed me off.

You setup your circles for various topics.
Neat idea. Complete failure.
I’ve set up social interactions for major companies. Basically any restriction on who can see what will kill the feature.
