Most people who are aware of the webcomic xkcd are also aware of explainxkcd, the (biased and crowdsourced) wiki which explains the jokes as they are often specifically geared to those mathematically inclined.
The comics can also be released soon after a news story (often science or technology related), so the joke needs explanation for those who years later may wonder what the hell he's talking about.
I've often thought that the Newspaper of Record, the Babylon Bee, could use a similar feature. One of today's satirical stories is a key example as to why:
SAN FRANCISCO, CA — Citizens braced themselves for yet another heavy crime surge this week after the city of San Francisco fined The Batman for putting a bright, obnoxious "Bat Signal" on the roof of a downtown building.
Now you may be thinking what I was thinking: that the city of San Fransisco either passed an ordinance banning those spotlights that bars and special events use to draw attention to themselves, or else some organization conducted themselves in a way to deter or help solve crime; either way city officials came down on them.
That is what happened, in a way, however it had nothing to do with searchlights or crimefighting. Instead, the city fined the owner of the building Twitter leases for putting the company's new logo on the building without a permit.
This was obscure enough that I could not know about it now...let alone the poor schmuck in April 2027 going through their archives and reading about a satirical story to a temporary news article of interest. Well, you're welcome yet-to-exist-schmuck: at least one Babylon Bee article in your newsfeed is now easy to understand.
