For XMPP to compete with Matrix there should maybe be a website that defines something like "XMPP Profile 2020" as an exact set of extensions that are required to be considered. Then list only clients and servers that fully meet all of that profile, and compare only the capabilities in the profile with competing protocols like Matrix. Without something like this evaluating XMPP as a user is tiresome, and it comes across as outdated, inferior and messy.

To compete with things like Slack, the website should be even simpler: A single choice of client / server that are known to work together perfectly, a big download button to an all-in-one installer that requires little configuration out of the box, and nice big screenshots of all the included features.

Same for IRC.
