I had a similar experience.  I ran my own XMPP server for several years, so that my email address also worked as an XMPP&#x2F;Jabber ID.  I talked to people across several different services, including an increasing number of folks on Google Talk.<p>Then Google Talk stopped federating properly.  Only a bit at first: things like presence notification didn&#x27;t quite work right, and adding people didn&#x27;t quite work right.  And in the meantime, Hangouts popped up, and offered a more seamless audio&#x2F;video experience too.  Most people I know stopped using Google Talk entirely in favor of Hangouts; the few that remained used it only while the gmail web interface more-or-less supported it.  Eventually, federation with Google Talk quite deliberately stopped working.<p>It didn&#x27;t take long after that before almost everyone else I talked to on it stopped showing up, even those who didn&#x27;t use Google Talk.  People had &quot;last seen&quot; times in the months, and if I wanted to talk to those people in realtime, I sent them text messages, or Twitter DMs, or Hangout calls.<p>So when I upgraded my server a couple of months ago, I just didn&#x27;t bother setting up the XMPP server again.  Not because it didn&#x27;t work, but just because it had nobody to talk to.
