Do you Twitter? The online tool lets you share your thoughts with the world in 140 characters or less, sort of like a mini-blog entry. And in addition to the social benefits -- you can let all your friends know how you spent your morning -- it may also be the best way to communicate with companies.
Starbucks, for example, updates its Twitter feed regularly, and even uses it to respond to customer questions. In the last day, it gave advice on brewing a proper cup of coffee, announced the company's new book club, and clarified the benefits of its new Gold card. The blogging company Six Apart and cable provider Comcast are also on Twitter. If you've found other companies, please let us know by commenting below.
