Actual insightful conversation on a variety of subjects. Especially current events, I notice this the most when discussing content updates in video games. While official forums exist a lot of the games I play essentially use their subreddit as a semi-official community with devs being active participants.
/r/eve and /r/pathofexile are great examples of this.
It’s hard to discount the success Reddit has had over the last decade or so positioning themselves as the “front page of the internet” giving people a forum to discuss all manner of subjects.
As I understand a lot of the hatred against Reddit and spez specifically comes from his attempts to monetize this phenomenon, not how effective/popular the site was.
I can’t wait for people who don’t have enough to fund the lavish lifestyles of people who spent their entire lives with too much because it’s not their fault we didn’t pull up our boot straps.
