A large portion of redditors are autistic and have very little social interaction, meaning that they don’t understand how people might actually joke around with others.

Combine this with cliche reddit humour (broken arms, sweet home Alabama, etc.) being so readily rewarded with praise on this site, and you can see why the redditors sense of humour may begin to deteriorate. Obvious satire such as this goes completely unrecognised by these socially stunted autists, and the things they laugh at become more and more specific to this site instead of actually funny things that non neckbeards would laugh at.

Overall, the redditors sense of humour is a fascinating look at how people can delude themselves. When you see someone type something like “Were your arms broken?” and they get the inevitable “Every fucking thread” reply, what you are seeing is two incredibly unfunny people convincing each other and themselves that they are funny. Always mocked and left on the outside of every social circle in every aspect of life (school, work, etc.) the sperglord is finally accepted. From this point forward, his sense of what is funny and what isn’t vanishes completely, to be replaced by an amalgam of overused memes and phrases uttered by similarly socially retarded outcasts.
