If you're one with the web2.0 trend, you've surely heard of Twitter.  Its the first generation of what's being called 'microblogging' and its used by thousands upon thousands of people to let people know what they're doing at any given point in time.  It's great for groups of close friends who like to hang out, it provides a perfect place to keep up-to-the-minute details of what might be going on.  Used properly, Twitter is a great platform.  However, if you're one of the people that use Twitter to update your every move at every moment of the day and someone targets you personally, you could be in a world of danger.

Don't panic, I have yet to hear of anyone using Twitter as a platform for malicious behavior, but its bound to happen sooner or later.  The candid release of information such as whereabouts and activities one is participating in can give your enemies like stalkers, ex-lovers or ex-employees out for revenge, or even child molesters (parents, supervise your children on the internet) far too much information about you and could put you in serious danger.  Here are a few simple rules to follow to avoid these things.

• Don't be too specific about where you're going, you can say where but try not to give times.
• If you want to get together with friends, send them a message requesting a more personal method of communication such as a phone call to work out details.
• Don't make a habit of posting every 5 minutes about what you're doing.  This could give your enemies clues to your daily routine which they could use against you, your family, or your property.
• Don't give details about where you work if at all possible, again it could give people an idea about your schedule and it lets them know where you are on a regular basis.

Of course, there are situations where one might want to give this information, such as if you're in entertainment and promoting show times.  This isn't as dangerous because you know there will be a crowd around in those environments and those events are usually on a more random schedule than work.

Whether you're using Twitter or Myspace or Facebook, you should keep in mind that the information you make available about yourself could be used against you.  Be careful about what you tell a mass audience, especially if you think you may already be a target.
