i want new social media to target teens/young people with some novel trendy feature, way i see new social media will only take off cz it is trendy to use and old people are not there and slowly everyone/old people starts to use. FB -> Insta -> Snap/jikjok or whatever It would be nice if that company later sneaked like better privacy, open protocol / interoperability with activity-pub or whatever. i mean people won't use a social media cz it respects privacy etc.
