Here is something I found on LifeHack.org. They post a list of important things that can help students get ahead after college. A very important one is the 4th one....Craft your own personna.
Here's what they write:
"In today’s world, one of the worst ways students damage their future careers is by sharing too much of the wrong kind of information online. Assume that everything you post online is going to be available to prospective employers, clients, or investors, all of whom increasingly turn to the Internet to research potential employees or partners. Keep the drunken stories either anonymous/pseudonymous, or marked as “private”, and be sure to build out public-ready profiles, under your own name if at all possible."So always be very careful about what you decide to post on Facebook and other social websites.
