XMPP and Matrix: Better or Different?
My opinion in advance: I think Matrix is neither better than XMPP nor the other way around: The protocols are just different but can be combined with their advantages (let's say X[M]PP) ;-) Every matrix server has the ability to bridge to the international standard XMPP and there is the way XMPP to Matrix too. So it is up to the administrators/decision makers to open this door to interoperability. There is no "Matrix vs XMPP" but a "Matrix with XMPP".
What do you think?
