I see nothing wrong with cyber-friendships. They can be just as valid, if not more so, then real-life friendships. Not everyone on the internet is a complete psycho who is out for your blood. For all you know, your real-life friend might be some nutcase who needs to be put away. If you don't wish to make friends on the internet, good for you. However, don't put down others who feel that they reap the benefits from this method of communication.
Not targeted at anyone here in particular. Just expressing what I am currently thinking about.
