Dell Inc. knows a thing or two about social media. The Texas-based computer giant has created three photo streams on Flickr, 26 pages and groups on Facebook and 34 Twitter feeds. These include a Facebook page for “US Consumer Dell Deals,” a Facebook Fan group entitled “I support Dell for choosing Ubuntu Linux,” and Twitter feeds offering special deals to small businesses.

Dell isn’t alone. Many other well-known companies are pursuing the marketing opportunities offered by social media. Ford, Target, Coca-Cola and Pepsi are some of the businesses on Facebook.
