A new practise is cropping up in HR departments and recruiters offices around the world. In addition to the typical resume reviews and background checks, recruiters are now beginning to search through your on-line profile.
By using personal networking services such as Friendster or Myspace and also through other avenues like Blogs and personal websites prospective employers can get a look at what you really think, without giving you a chance to provide that all important “proper context”.
The lesson in this really is very simple. If you don’t wish to be known for strange antics or strong views on sensitive issues, there’s no reason you have to tag the articles with your real name. If you’re going to maintain an virtual presence representing your not-so-virtual self, make sure that you have comport yourself in a manner in which you wish to be recognized… If you don’t want a potential employer to know about that time you and your buddies got drunk and crashed a car into a dumpster, don’t talk about it online… (or don’t use your real names. 
)
Don’t give anyone the opportunity to wonder whether they’re hiring the spit-polished version of you that they met at the interview, or the spit-up version of you drunk in your friendster photo gallery. Really people… a little common sense!
