I want to see more niche social networks that are only for one thing. I actually really like Strava which is for workouts only. There’s no way to share pictures of inspirational text. I’ve never seen anyone abuse the platform by sharing a run that is actually 0.1 miles plus a rant about Fox News or anything like that.
If I were independently wealthy I’d spend my time building a newsfeed for musicians to share music things where it’s similarly impossible to post pictures of text or news articles. You’d need to be vigilant to prevent it from overstepping the way LinkedIn did.
The challenge is that if you can share photos or video or links at all, it becomes terrible.
