Social networking is the latest way to stay in touch with family and friends, reconnect with old acquaintances, and make new ones. People from all over the world who share your interests can make contact via sites like Facebook, MySpace, Ning and many more. To get the most out of your experience, pick the site the majority of your friends use. Two years ago, it was all about MySpace, which seems to have been left in Facebook's dust. Who know what it will be in another couple of years?
Another way to stay in touch is Twitter, which allows you 140 characters to tell what you are up to. Twitter postings are called tweets. Celebrities, Senators, businesses and just plain folks are happily tweeting about everything that comes to mind. Check out http://twitter.com to see what all the buzz is about.
BEWARE. Remember that everything you post on the Internet has the potential to be made very public. Some employers check up on Facebook accounts and make hiring decisions based on what they see there. Rude, stupid or criminal behavior can come back to haunt you. Be careful what you share and with whom. To much personal information for all the world to see is not smart.
Overall, however, social networking can be fun and enlightening. Just exercise some common sense and enjoy yourself.
