Have downloaded the Beeper app which seems to nicely integrate a few of my favourite chat protocols. I noticed Matrix in the mix however.

I've heard, obliquely, of Matrix, but just assumed it's yet another messaging protocol. Would appear that's not the case though? Where would one get started? Why would I even want to use this vs the multitude of others? Is there an NZ Matrix server? Does it even matter? Why did the last season of GoT go so badly off the rails (oh wait, we know the answer to that one)...

TIA!
