Social networking sites are just plain fun. Once you set up your profile page, other registered users from around the world can look at your profile and decide whether they want to get to know you. If they would like a chance to be friends, they simply request that you add them to your friends list. Of course, you can look at other people's profiles and make requests, too. Where else can you make friends with a sales executive in London while getting to know an unsigned blues band in Colorado?There is an old saying, though, that goes, "Make new friends and keep the old" The same applies with social networking. You can look up a high school friend or a college roommate and have the chance to reconnect. Granted, you may quickly remember why you haven't stayed in contact over the years.
