They said this about Reddit for years. Even now most people I know IRL have a vague understanding of Reddit. 5 months ago my dad was in a phase of obsessively consuming Skiing content and he signed up for Reddit and found other subs to match his interests.

Anyone who cares about this sort of social media shouldn’t have an issue. And keeping out wider masses is what makes these platforms so engaging when they hit the young/mature stage, IMO
