This is a pattern now in greater society, one of the (arguable) downsides to tech is that the bar for publishing or organizing just about anything has been lowered - so now it isn't tenured professors with years of experience in academic best practices giving carefully prepared talks summarizing months of research, it's programmers with no formal education presenting whatever in a totally casual manner.

Don't get me wrong, that it's casual isn't necessarily a problem, but literature, journalism, even scientific publications are all seeing wider distributions of quality now that it's so much easier for the average person to find a platform. And I think the predominant expansion is at the lower end of the distribution given that there was previously a strong effective selection pressure for quality, since it took substantial resources just to publish any media.
