Readit NewsPersonally I find XMPP much makes sense. Sure it's this weird streaming XML thing, but there's a request/response pattern (IQ) inside that seems fine. I love how nicely it composes: accounts have a tree of nodes they can define for whatever content they want, which is a sensible & flexible base. Then there's pubsub, and ACL capability specs on top of that. Everything stacks relatively sensibly. The past decade has seen some good XMPP Enhancement Protocols (XEP) to create best practices & recommended feature sets.
It was such a small jump to create a full "everything app" atop XMPP baseline capabilities:

It's unfortunate that the top rated comment is uncontestable blanket desparagement. Can we raise this from a low criticism to something respect-worthy?
Presence. That's the colored dots indicating "is somebody online or not". The traffic needed to maintain presence scales by N^2, and in any large-scale implementation, the traffic to maintain presence data completely dominates anything useful.
Not to mention that for the past 15 years or so (ever since everybody has a connected cell-phone all the time) the whole idea of presence (am I online or not?) is either meaningless or just badly modeled.
So the result is a protocol which spends tons of bandwidth and battery maintaining metadata that is functionally useless. That's why the real world has run away from it as fast as possible.
a) there is probably several orders of magnitude more Perl code running out there in the wild than Rust?
b) the TIOBE index was ever meaningful?
I remember at a former company, we had a major migration away from Perl 12 years ago. The Perl code base was considered extremely ancient even back then.
Now, I don't actually believe this, because that puts Perl way ahead of Rust (currently at #18). So the big thing I'm taking away from this little research post is that I no longer trust the Tiobe index. Too bad - it felt pretty reliable for a long time.
That barely registers as a blip even if you're hosting your site on a single server.
