Is privacy really privacy?

In Alan Finder's article, "When a Risque Online Persona Undermines a chance for a job," he talks about the digital world, mainly the Internet, as a tool for company and even schools to look at how a person might be acting in their everyday life. Mainly, a job interview is one of the most important thing in your life because it may make or break what you do in your life. Now, facebook is one of the main culprits as to why people are getting turned down from job opportunity because of the fact they people put inappropriate pictures up on pages. Now, for a company, they might come of as; well they may only focus on how I perform in the interview or they won't look on my facebook or my space because it's blocked. Well, to tell you the truth, you may not be completely safe because if a company really wants to find out who you are; they will. For me, I'm trying to get an internship over the summer and I don't want anything to mess it up. I do have a couple inappropriate things on my facebook as well as I do have it blocked to only the people I'm friends with, but just to be sure, I probably will delete those pictures. I don't want something in my past to affect my future that I've work hard for.
