Curate, connect, and discover
One of the few good things of reddit that is criminally underappreciated is Wandering Stoner Posts. Written by someone who has never been to this community before, doesn't quite grasp what exactly is going on around here, and felt compelled to make a post to inform everyone about it. They do this because they are also really, really high.
I honestly judge the community of every subreddit by how they respond to these posts. The truly friendly communities will be friendly, and the ones responding with hostility are hostile as a whole. The quality of your character is reflected in the way you respond to the confused weed pilgrim.
Reading those posts going "hey I just found this sub and I'm sorry but I'm super high, I don't get what you're doing but you guys seem cool" feels like having a bumblebee fly up to you, and inspect you for a minute to make sure that you are not a flower. It's ok, you god's gentle little creature, I understand that you mean well and that your brain is not very fast.
