In a clash of enterprise social collaboration, Salesforce has the bigger announcement, but product doesn’t ship till the second half of 2013. Salesforce says it will be getting into the hosted community business, enabling companies to create private social networks to collaborate with remote employees, customers, and their supply chain. Companies like Jive and Telligent are well ahead of the big guy on that front, even if Saleforce says Chatter has 150,000 paying users. Yammer gets a fairly minor upgrade, with new email integration features and connections to HootSuite and a variety of other services. Salesforce also announced that its Buddy Media acquisition closed. Though that’s a social media marketing play, it has nothing much to do with these other work media or enterprise collaboration tools.
