After conducting experiments in beta since February, Salesforce states that their products, Chatter is ready for use.
Chatter has been available for workers who have subscribed software or products or products that use theSalesforce.com Force.com platform without any additional subscribing. Companies can also use Chatter for additional workers who did not use these products with $ 15 per month. Chatter can be used on PCs, Macs, iPad, iPhone, and BlackBerry, and planned to be added for Android applications. But until nowSalesforce.com does not support instant messaging yet.
