#6: Not clearly identifying your brand's Twitterers
It is important that, somewhere on your main site, you have a "directory" of people from your business that tweet on behalf of the company. It is also important that these people's bios are descriptive.
Companies like Dell use the word "Dell" in the user name (richardatdell, lionelatdell, etc.).
Kodak employees clearly identify themselves on Twitter via a visual branding profile image. Note the brand logo on the lower portion.
