I’ll go first: r/kitty. One of the hundred grillion cat subs back on Reddit, the culture in this one was you posted a cat picture, and the only word allowed in the title or in any comments or replies was “Kitty.”
Someone is using that subreddit for covert communications, I just know it. Either on the level of “if u/PM_me_your_nostrils posts an orange cat, we attack at dawn!” or there’s some steganography going on with the pictures, but that subreddit was too stupid to be as active as it was.
The ceilings one is way simpler.
When you spend a lot of time in a place with low ceilings it makes you subconsciously feel trapped. After a while of it your actions and behavior will likely start to reflect that and you will probably be less likely to do anything that you can for your future.
You don’t get that in a place with higher ceilings.
Interesting.
