Not Google, because if it becomes even mildly successful Google’s insatiable avarice will ruin it, and if it doesn’t become successful, Google’s insatiable avarice will ruin it.
The potential upside to this would be that if gets shut down a snazzy instance could have an advantage in capturing a lot of the migrating users as the users could pick up where they left instead of starting over in a new service
Google Talk used to be XMPP based, and it was awesome.
Unfortunately someone managed to convince leadership that they needed to create a new chat app with a proprietary protocol, and everything went downhill since.
I mean, to be fair, among all the various fields Google has ever entered, they have a comparatively good track record with chat applications, in particular: Google is, in fact, pretty much known for their keen understanding of how to maintain and grow social networking products (in general), and (of course) chat applications (in specific).
Is this sarcasm? They couldn't get Google+ anywhere even by gutting YouTube for it and they have like a dozen different chat apps where Noone knows the difference between them
(Do I really have to explicitly mark sarcasm these days? I went to great lengths to make my comment drip with flowery language like "among all the various fields Google has entered" on my way towards reaching a conclusion that would indicate Google is somehow better at chat than search, and yet I still got a response "is this sarcasm?" :/.)
Sounds to me like this doesn't correspond at all to google's main interests, being selling personal data from people and publicity, because first of all, how would they compete with whatsapp having more than 1 billion users in first place?
