The new offering could chip away at Microsoft’s lead in the collaboration and email messaging market, where five years ago Microsoft Outlook e-mail and its newer SharePoint collaboration software began to surge past rival IBM products, O'Kelly said.

Connections combines five components: member profiles, activities, blogs, communities and “dogear” IBM's word for how users identify and share Web bookmarks with colleagues. Connections uses the popular Web navigation technique of “tagging” to help users track popular discus sion topics and figure out who may have expertise on any subject. The software provides a way for individuals to quickly set up ad hoc groups to collaborate on projects, storing relevant documents, e-mails and Web sites together. Each user can publish blogs to share ideas with colleagues. 
Microsoft has 200 million Outlook users and signed up another 80 million licensed users of SharePoint software, he estimated. IBM officials see a shift in focus from the quest for personal productivity that characterised computer advances of the 1990s to the “team productivity” which Web-based collaborative tools have begun last year IBM said Lotus Notes had 125 million users. Adding in collaboration software, Lotus users number around 150 million . Microsoft has 200 million Outlook users and signed up another 80 million licensed users of SharePoint software to enable in recent years.
What Web 2.0 has demonstrated is that self-defining communities often do a better job of locating relevant information,” IBM software chief Steve Mills said.
This helps with the rapid identification of expertise and experts. Lotus Connections will become generally available later in the first half of 2007. Pricing has not been disclosed.
