But you already know this, right? If not, I recommend reading this article from LawJobs.com very closely (particularly if you’re looking for a new job):

"Plug a prospective employee’s name into Google or any other Internet search engine, and you might be surprised at what you find. Web pages may tell hiring attorneys that the person they just interviewed wrote for an undergraduate newspaper or belonged to a specific sorority, but the Web may also reveal the recent interviewee’s drink of choice and dating status.

"The advent of social networking Web sites such as MySpace, Facebook and Friendster have added a wealth of previously personal information to the Internet, some of which job seekers may prefer to keep private and out of an employer’s hands.

"No more is an interviewer’s information about a job seeker limited to a résumé, cover letter and professional references. Now, it seems that Google [& other search engines] can produce more information about a person than his or her FBI file. And therein lies the rub."

BTW, a perfect example of how easy it is to find information on the web is the answer to this detail: "Author Michael D. Mann is a litigation associate in the New York office of a major law firm that asked not to be disclosed."
