> And it doesn't work at all with low power mobile delivery. (It was invented before the iphone.) This is plain untrue. Yes it was invented a long time ago, but thanks to the extensibility it has evolved over time just as the way people use it has changed. This evolution is a healthy and necessary part of an open ecosystem. I know it frustrates people that modern features don't work in stagnated clients such as Pidgin and Adium, but modern clients support all the things you would expect. Servers and mobile clients have supported mobile-friendly traffic and connection optimisations for many many years now. > There might have been political reasons why google dropped XMPP, but it would also make sense as a purely technical decision. Google contributed extensions to XMPP, the same way they contribute to other internet standards. I think they were quite comfortable with this. The XMPP-based Google Talk was their longest-running messaging solution after all...
