The value of Twitter for business

Twitter, if implemented correctly, can be a great way for companies to enter the social media realm online and engage consumers.  I have seen it first hand with 3 clients at the digital ad agency I currently work at.  Find "key twitterers" for your target audience, and follow both people that are following them, and the people that the "key twitterers" are following.  If you are targeting Moms, follow people like Martha Stewart, Oprah, Ellen, and then the people associated with them.  If you are targeting sports fans, follow Twitter accounts such as ESPN, FoxSports, etc.  This is allow you to build a Twitter account with a relevant audience, who will be more likely to accept your message, and engage your brand/promotion, etc.
