My list is separated into 30 separate categories to help find your area of interest whether it is networking, security, messengers, video editing, education, etc. It is also backed up to the Wayback Machine for future reference.
I update this page as and when something new of interest crosses my path so there are usually bi-weekly or monthly updates.

Thanks have added Gajim as I use it, but put link to other clients as there are many XMPP apps.

XMPP is actually a great protocol that has expanded over time with lost of additional functionality, including secure networking. It has both channels and blog subscriptions (not supported by all clients). The only other protocol I know of that has extendible features like this is Nostr. Both really put ActivityPub to shame apart from the federation aspect. Actually wondering if XMPP has a Lemmy/Reddit type link aggregation with voting.
