The "new friends do not get to see old posts" seems very limiting, I would certainly want the option of being able to share some of my old posts with new friends, given that often new friends are made because of some overlap in real life history.
I understand that this platform is perhaps deliberately not trying to attract strangers, but other platforms that had taken this stance eventually all faded away because all my friends want to play at where the parties are at, and those tend not to be private networks of this sort. It might be possible to avoid this demise if this network grows to be sufficiently large, but it's hard to grow when all existing contents are invisible to new users.
> Posts are shared with all of your confirmed friends once published (let the people in your life know what you’ve been up to)
That part also seems weird to me, and also why I never really post anything to facebook these days (even if I used it more than once a month). Unless the things you're writing are stupidly generic they won't appeal to all your friends, especially since "social media friends" these days also means family, coworkers, acquaintences, that one guy you did a college project with and never talked to again, etc. Not actual friends.
I know which of my friends are interested in what, and I can share what I know they'll be interested in hearing via DMs, leading to more productive discussions. I'm not sure what the appeal of friend-only self posts even is these days, unless you're planning a get together of some sort.
If you're making a self post, there must be people that you don't know about that can see it, so there is some chance that you'll find someone new that's interested in what you posted. E.g. posting in fb or discord groups or in public like on reddit or here.
