Or you could be smart and avoid social sites like the plague, because surely they are. Where the numbers mass, the attacks ensue. Never forget that social sites are a prime target for all types of scams, virus's and other potentially harmful things, especially for those who don't know what to expect or look for. May I suggest the best, most secure, reliable social site available. You may have heard of it.... it's called Life.
i know a friend that got a 50k+ job from a large corporation through facebook so your advice is a little patchy. instead of avoiding it you should say that people need to watch what they say and do on facebook.
