XMPP is a moderately well-known protocol for instant messaging. It is not as technologically advanced as many popular instant messaging tools, but it works if you want to just setup a small chat room for your friends, and it has low resource consumption.
The problem with Jabber (that is a network of machines communicating over XMPP) is that there are so many incomplete clients, very few of which are capable of providing a wholesome experience.
The well-known website serves as a dashboard for tracking one particular feature the authors are very fond of, however, I wanted to have a similar table for features I personally care of. So I forked the website and sometimes even update it a bit.
Pull requests welcome.
