Recently I attended some career related classes and the subject of liability came up, and it was a real eye-opener.
basically be aware of the fact that things you post here, on your facespace mybook and all the other places you may post audio, video, text entries...all are potential avenues to create a case against you. Youtube could be especially damning considering we tend to post those funny (to us) close calls, that could be twisted to show you are a risk taker and loose cannon. I never thought of how much more public every single electronic call, message, etc are forever recorded and subject to scrutiny.
unfortunately there are those that are out to get you, and the more wealth or property you have the more you should consider the above.
