Sort of. Usenet was used to the influx of new University student accounts that joined in every September without understanding the norms or culture of the usenet groups they started posting to, and it took some time for them to learn the expected way to behave. But things "went back to normal" until the next September with it's new batch of uni students with internet access started showing up in usenet. As the second half of that jargon file entry goes on to say, when AOL users started showing up, it became the "eternal September", since there was a continual deluge of new usenet users without any respite where they'd learned to fit in with the culture. At least that's my memories from being a regular on comp.lang.perl.misc, aus.motorcycles and the scary devil monastery back then.
