companies on twitter

David takes a look at how both Southwest and Zappos (two companies known for their impressive customer service and creative use of social media) are now leveraging Twitter.
Zappos is well known for their amazing customer service. Southwest is well known for having one of the most engaging blogs in corporate America. In fact, Southwest is so dedicating to using their blog to have conversations with their customers, that they often take business ideas to their core customers before putting them in place at the company.
