The idea is pretty cool! I think it has potential, as when I used instagram, people seemed to enjoy the “closed friends” feature, and also created separate IG accounts to follow close friends.
Thanks! It's been interesting as I used the first prototype to learn how to code. There's been breaks between then and now but that was 18 months ago - a lot of the premises for building Circles have been adopted by IG. Close Friends, Send to Groups, DM focus and easy account switching.
