I don’t like any because of privacy concerns. I know I can make everything private to friends only, but I don’t like everything being public by default. e.g. what if I commented something on a friend’s private profile, and then they make it public later? or data breach or something, too much to care about

I have my apple watch record to my iPhone, and I manually decide what to export (in my case, it’s just day + mileage values uploaded to fiveoutofnine.com) or post runs/workouts I want to share, like I do here

not fit for everyone, but I like being able to fully manage my data for something like this because I see 0 benefit to sharing everything by default. don’t really care about the social aspect either because I can just post on other channels or tell people directly when I want to

agree with your concerns (privacy) but i think the key point of a "social" platform is the ease of reciprocity: it is much easier for friends to share their data with me as it is for me them on such a platform versus methods we build ourselves (even if tooling is easy and free).
