I was very pleased to see Russell Beattie's recent posting suggesting that his employer, Yahoo! should consider supporting Jabber/XMPP now that Google has decided to support this open IETF protocol. After years of closed and proprietary IM networks, it may be that we can finally start looking forward to the same ease of interconnection that we have in our email networks. (Yes, we need to address the spam issues in IM too...) We've been using Jabber/XMPP in our PubSub Sidebars for quite some time now and we're not surprised at all that Google has found this protocol to be a good foundation to build on. I'm hoping the other services follow suit soon.
It's time to start eliminating the walled-gardens and build systems more in line with the way the Internet was intended to work! Standards, not proprietary systems, are what we should be in our critical communications systems.
