I'm the author of an April Fool's Internet Standard, AMA
Let's get the AMAs kicked off on Lemmy, shall we.
Almost ten years ago now, I wrote RFC 7168, "Hypertext Coffeepot Control Protocol for Tea Efflux Appliances" which extends HTCPCP to handle tea brewing. Both Coffeepot Control Protocol and the tea-brewing extension are joke Internet Standards, and were released on Apr 1st (1998 and 2014). You may be familiar with HTTP error 418, "I'm a teapot"; this comes from the 1998 standard.
I'm giving a talk on the history of HTTP and HTCPCP at the WeAreDevelopers World Congress in Berlin later this month, and I need an FAQ section; AMA about the Internet and HTTP. Let's try this out!
7168 is my only foray into writing an Internet Standard RFC. If you have a good idea for one, you should definitely get in touch with the RFC Editors; I found them very approachable and willing to work with my idea, moulding it into a document that's compliant to their (admittedly old-timey 60's) documentation standards.
