To OP and the few other comments sarcastically dunking on the blogger for just discovering RSS: why? It's not exactly drowning in advocates today, and there's basically a whole generation that wasn't around when Google killed off Reader. What if we treated advocacy like this like the good thing it is?
You make my heart hurt, you're so right. It's getting harder and harder to find RSS or Atom links on sites. The more people rediscover these technologies, the more chance there is that site developers will continue to provide them.
It would be fantastic if more people would rediscover Usenet, and IRC, and ditch the shitty knock-offs like Discord. There's a pretty big contingent advocating for Jabber, which I'm ambivalent about, having been there when it started and when it (effectively) died and being very conscious of its flaws and limitations... but, still, these are all open standards and old-school internet - sometimes pre-web! - and they're often still better than the commoditized successors.
Embrace and encourage the new infusion of youth! Gate keeping is a very post-eternal-September behavior.
Yeah, there was, and probably still is, a bunch of warez trading on Usenet. But everything that was good and holy was also on Usenet.
Anyway, plebes won't show up there anymore because nobody runs free nodes anymore, and the worst of us are so used to being products the idea of paying for a service is a foreign concept.
Usenet existed long before the Eternal September. It survived that and the subsequent decades; it's never been some sort of secret haven - it's been a haven only because it wasn't trivial to use, web interfaces for it never caught on, it started costing money to be on, and these are deal breakers for the people you don't want on Usenet.
Well, that rule has been mostly tongue in cheek as you are probably aware, but perhaps Usenet will once again become useful to more folks. I have never veered away from it since I discovered it in the late 90's. I suppose that makes me a part of the ES group? I'm quite glad to have discovered it. You do now have to pay to use it, but the cost is mild and the tools are all modernized with plenty of web front-ends out there.
I stay away from Usenet because I'm particularly susceptible to it as a time sink. It's worse than Lemmy, than Mastodon; I can spend hours in Usenet, and I'm really incapable of not doing that when I have access to it.
