The Intra (Social) Net
Although it is difficult to quantify how many companies use internal social networks, NYT finds that a number of corporate software companies are offering various systems -- some free to existing customers, others that charge a fee per user. Salesforce.com is a top provider of corporate social networks, and claims that 80,000 companies now use its corporate social network, Chatter -- up from just 10,000 when it was introduced a year ago.
Yammer, meanwhile, said its service is used by more than 100,000 companies, up from around 80,000 a year ago. Other providers include SAP, Cisco Systems, Socialtext, Jive Software and SuccessFactors.
