As the title says. I thought that was brilliant on Reddit, just checking people's profiles would lead to some cool discoveries of communities I would have never thought of by myself.
Is this a feature somewhere?
Edit: of course users have the option to not show these, no I don't want to violate anyone's privacy
It does if you turn it on. Might be enabled by default for new accounts of course.
I logged in Reddit in order to check, there's an option to show communities you are most active in (and that's enabled by default and not available on old.reddit.com) but that's not what OP asked for, as I guess it lists communities I comment and posts the most, right?
No, that's the feature I mean. You got it right. It never disclosed everything, just the most active ones.
