IBM's Lotus Connections, which IBM dubbed "business-grade social computing," lets business people post personal profiles about their expertise and interests and Web logs for ongoing commentaries. It also lets them connect with like-minded communities for online work collaboration, manage group products online and share documents and Web sites through bookmarks.
"Social software tools will become so much a part of the fabric of an enterprise's collaborative environment that it will be like air -- enterprises won't be able to imagine life without it," IBM said in a statement.
IBM did not provide pricing information or forecast sales. It said shipments would start by June.
Microsoft Corp.'s Windows SharePoint Services, a 5-year-old product with 85 million users, added social-networking features in its latest version, unveiled in November.
