Facebook’s membership soared over the past three months, CNET News reports, as the social networking giant gears up for a possible link-up with Salesforce.com on the corporate side.

Specifically, the company “grew its active membership total from 90 million in early July to 120 million now,” said Facebook Chief Operating Officer Sheryl Sandberg at Salesforce.com’s Dreamforce conference, according to the report.

“We got more (members) in the last three months than in the first three years of our existence,” Sandberg said. Facebook has more mobile options in play than LinkedIn, the social network that’s traditionally viewed as the most enterprise-oriented among the leading services.
