However after Google Talk was replaced with proprietary Hangouts protocol we had to look for other options.
Telegram fits our concept just right. Let's see what other people think. You are welcome to participate.
It's also great to hear that it started out using XMPP, maybe Jaconda can bring XMPP back by allowing discovery based on GitHub accounts :o
I don't see how you _had to_ look for other options
(still: I agree how looking at other options is the wise thing to do, given that Google+XMPP seems to be a -very- slowly sinking ship)
People that moved to Hangouts aren't available on GTalk (the xmpp part). I run my own XMPP server, people that have ancient Android 2.x mobiles and don't buy into the G+ nonsense can talk to me. People with more modern systems/that 'upgraded' to Hangout cannot.
Since my server cannot magically filter these people I came to the conclusion that Google _doesn't_ support xmpp, federation or not, for most of their users anymore.
(If you manage to access GTalk again, for example by running the GTalk thingy in GMail/the browser, you can talk to me again. I've got a hard time making my friends do that to contact me)
For all intents and purposes Google's XMPP support is broken.
True, but this is "only" a client problem. What is first and foremost important is the support server-side.
This ugly situation is just like if everyone suddenly decided en-masse to stop using their XMPP client of choice.
This is partly "waking up to reality" for the XMPP community, partly a huge tragedy for the lack of diversity in how people (used to) communicate over XMPP
...but none of these thing would impede Jaconda's users to receive notifications on their desktop or their mobile.
(If anything, I'd consider developers (Jaconda's users) more likely to have an actual XMPP client, rather than strictly relying only on what Google provides by default)
They just (~now~) sent out messages to GTalk users, telling them that Gtalk-the-desktop-app support will be terminated on the 16th of February, like .. in a couple of days from now.
For me Google's xmpp support is nonexistent, I understand Jaconda's attitude.
But I waited until today (17th February) to reply, and... well, Google hasn't shutdown its XMPP servers yet, apparently
Go figure...
All these newfangled alternatives usually rely on the Google services' push notifications api afaik.
Also, sending files over XMPP has pretty much always sucked - there are a bunch of incompatible ways to do it and it's always been hit and miss depending on which client your chat partner was using, network topography, etc.
