Who, do you think, should be the one to give you the permission?
Some sort of site guidelines and a UI that makes it clear. For example, if there were categories, it would be clear that the posts in the category are acceptable.
I'm far from a conformist, but I think norms definitely do have a purpose. I don't really have any strong opinions on permission culture in general that I could articulate well.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one.
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
