Resolved: Google Talk & AIM interoperability not working
UPDATE 3/15: This issue has been resolved and Google Talk/AIM interoperability has been restored.
Google has temporarily disabled the ability for a Google Talk account to talk directly with an AIM account while we work out an issue with spam accounts. We’ll update you when this has been re-enabled.
You can still use your Google Talk account within AIM to talk to your Google contacts.
