I have just been thinking that a similar principle applies if you are the employer or entrepreneur. Your customers are also active on the Web so your online presence could easily impact on your relationships with your customers (and prematurely end new relationships with prospective customers). At the same time, your activities on the social web could serve as a really useful way to build and strengthen relationships.
ITWeb has quoted me in an article titled “Facebook can get you fired” which looks at how your activities on sites like Facebook can create problems for you back at the office. The article also includes quotes from Deshanta, Cerebra’s content manager so be sure to read the article.
