Strava is the closest thing to effective social media that I use, because it is 'slow'.

You create 'content' by doing something orthogonal. You pay for access vs selling attention for ads. You only look at Strava when you are working out, so engagement is authentic vs contrived/performative. I care about my friend completing a run because I know they did it.

One of the best thing they did was allow the chance to add photos.
