This board is slow, even on its busiest days. Sadly, this means there are barely any memes. When a board has high activity, the percentage of new shitposts may stay the same, but the magnitude (actual number of shitposts) increases. When the shitposts reaches critical mass, memes are born. This is the fundamental theorem of dark memeology, and is what you'll find on most boards. What we have in /n/ is light memeology, the slow, slow manufacture of memes which doesnt sacrifice post quality. It acts as quality control too, with only a few memes every moon through this process, you can be sure its the funniest ones.
Personally, I like stuff about the ignorance of normies regarding trains the most.
