IMHO, it is FINE to include niche jokes in your stuff as long as:
1) It's easy to Google
2) It's a cool thing. So when they Google it they go OH SHIT THAT'S A COOL THING I NOW KNOW THANKS WRITER PERSON
Because the nice thing about written comedy is people can go off, Google, fall down a rabbit hole, come back and enjoy it even more
If the joke requires something that CAN'T be searched, though, then you're just being a snob.
