Twitter increasingly used by business

There are some huge companies currently taking advantage of "Twitter" for customer service.   

Today Azzurri Communication's (the parent company of Callmedia who I work for)  is about to start communicating with customers via the use of tweets.

I have started to build a list of companies embracing Twitter for providing customer service and communicating information:

• Dell
• Ford
• Samsung
• Whole Foods Market
• Starbucks
• Jetblue
• Virgin Atlantic
• Southwest Airlines
