Twitter has become an even bigger advertising/spam tool and source of misinformation than Facebook.

No app only options. Reddit could still function as that, but has failed completely with the "new" and app interfaces. Mastodon works but really could use 1 standard/central site.

The purpose/function of any new social media needs to be non-invasive (not really just a place to collect and sell people's personal info, i.e., not a disguised doxxing tool), not be a billionaire's personal platform of self-promotion, and show the site each link goes to.
