Epistemic vibes: considerable anecdotal evidence.
I am writing this post because when I first posted to this forum it felt cringy. Which is normal, because it takes a while to learn the group norms. But no one told me that, and I thought I was unwelcome and refrained from interacting with the forum.
The comments below the linked Facebook post showed that this might be a universal experience. But not hearing opinions from newbies is bad because they can bring a lot of interesting and new perspectives from outside.
So read the guidelines, but other than that, feel free to post. Your tenth post will be better than the first.
