Relax, CRM vendors. Google is not getting into the customer relationship management business (CRM) anytime soon. But they should. Google seems to understand the Social CRM needs of small and medium sized companies better than most.
Users are able to opt out of this feature. And if your company uses Google Apps, then your administrator can take control of the messaging. More importantly, we learned that these unsolicited messages will show up in the Social tab of our Gmail inboxes, and there the message will die unless you either respond to it, or add the sender to your Circle.
