Google announced this afternoon that its users can now login to their AIM accounts and chat with both Google Talk and AIM buddies at the same time. Chat transcripts, contact list sorting by frequency of contact and other GMail chat features will be included seamlessly. I don’t see this feature yet myself, but I only saw the new colored labels for GMail an hour ago so perhaps I’m among the last to get everything.
I don’t know that this can be called interoperability, but it’s a nice touch. No corresponding announcement about logging into Google Talk through AIM has been made yet by the AIM team – who apparently haven’t been up to much since announcing their quiet support for OpenID more than a year ago. I tease, but come on guys, can we get some fireworks occasionally?
