proof please. Checked the top 3-4 xmpp servers last summer and they almost died.
IRC looks 1000000x more active.
My mention of thousands of servers is not related to public chatrooms however. There are a bunch of public servers which you can register accounts on, but many more private ones (that federate) run by businesses and individuals and other organisations. A quick shodan search reports 55,760 unique IP addresses speaking XMPP publicly on port 5269 (the default federation port): https://www.shodan.io/search?query=port%3A5269+http%3A%2F%2F...
OK, "324 Kuketz-Blog (email@example.com)" seems like most popular jabber channel, right?
Here's the #freenode top in this moment:
And it's ONLY first 3 top channels.
So, the facts matters.
Indeed. Could you also provide the number of 1:1 chats and private groupchats running on freenode, then? Both of these are way more popular use cases for XMPP than public rooms.
On Matrix practically everyone is matrix.org. The other public servers I tried are relatively slow and suffer hickups when joining rooms.
On XMPP, many people run servers in their companies, projects, or homes. Which are the "top 3-4 XMPP servers"? I probably do not even know them.
But you are right: XMPP is used mainly for IM, i.e. one-to-one dialogues or smaller, non-public chatrooms. I'm not aware of any huge, public chatrooms in XMPP, and for that I'm on IRC — via a gateway from XMPP called biboumi.
