XMPP dev and XSF member here.

I'm using XMPP for chatting of course, but also for blogging (my blog is XMPP based), A/V calls, events organization, file sharing, photo albums sharing, as a remote (with ad-hoc command, I've even built an specific UI to control MPRIS supporting player). I'm building an agenda, a forum, a generic list tool (TODO, shopping list), and other stuff.

I'm using Snikket to host a small server for family and friends, with accompanying mobile clients.

I've also built an XMPP <=> ActivityPub gateway (soon to be released, but dev version is already available), so my blog is accessible from any AP supporting client, and I can access the AP ecosystem (including events as seen in Mobilizon).

There is Slidge IM if you wanna talk to legacy network such as Signal, Whatsapp, Telegram, Discord, Mattermost, Steam, Skype, Facebook Messenger, Matrix, VoIP.ms.

There is Biboumi if you wanna talk to IRC.

There are old and new email gateways on the work (I'll be working on one myself).

XMPP is used in many fields (from healthcare to games), you can have an idea at https://xmpp.org/uses/instant-messaging/ but I have the feeling that this list is not up-to-date and is incomplete. I think that it's used in Fornite for instance.

So yeah, we may not be the best for marketing, and we not have as much resources as we should, but XMPP is still well alive and kicking!

edit: Fornite is actually mentioned at https://xmpp.org/uses/gaming/ .
