Reddit has never been good for "truth". It was good for discussions for the period between the end of forum culture and the 2016 presidential election, but since 2016 the website has been increasingly moderated to the point that right-wingers, moderates and most non-US users aren't represented more than a tiny percentage, and it is a mass market appeal website.

Quora was good for more centrist and international comments, but it too has been destroyed by poor development combined with politically motivated moderation.
