Microsoft SharePoint and Socialtext's namesake offering are highlighted in a discussion of the use of such consumer tools as wikis and social networking in business. Social networking connects people online through their online acquaintances, and wikis allow multiple individuals to change a document on a Web page and to then track the changes. In the past 18 months, Intel, Quark, SAP, and IBM have started experimenting with techniques that include recordings of meetings that can be downloaded to iPods, blogs where staff can talk back to their bosses, and internal Web pages that permit users to read their colleagues meeting notes and also add their own. Gartner estimates that companies spent under $50 million on such tools in 2005, while at home many staff meet people on the Web, post photos in shared online albums, and listen to podcasts on digital music players. They use the media players, wikis, and social networking tools less at work, relying more on personal contact and extensive use of e-mail. Companies are playing catch up through the use of free or low-cost software that is available online. Instances are described in which a Wikipedia-like Web site and Intelpedia have proved useful. IBM encourages employees to bookmarks internal Web pages that are useful, and Dogear collects all the bookmarks in a single location so that employees can find information through keyword search. Another user describes how he signed up for Socialtext without the permission of SAP IT, but the SAP IT department, seeing that the wiki was a success, decided to support it.
