I think some times a place can be overly curated or structured. We forget that people are perfectly capable of just ignoring the content they don’t want to see and it can be selfish IMO to just stifle content just because one personally doesn’t want to see it.
The mail day posts are about people sharing their excitement of getting a new throw, particularly novice throwers.
I realize that some people will view that as pointless or not adding anything to the discussion, but the thing I love most about this community is how supportive they are and mail day posts are a great way to just tell someone “wow, very cool, atta boy!”, to give them affirmation and to share in their excitement.
