What app features do u want?

I am a solo founder, working on a social app. I dont have anything to promote or offer, just curios if there any features that would make you want to use a social app.
There is always the whole "why should i move to xyz if i have twitter/reddit/insta" so thats why i wanted to ask what feature could (if at all) would make you want to try (and hopefully use) another app?
