Have you made friendships that exist exclusively in cyberspace? If so, how are they different from f2f relationships? If you have not formed cyber relationships, why not?

I have never made friendships that exclusively exist on cyberspace, however I feel that most of my relationships continue through the easy acess of cyberspace. Today, that is huge part of how we communicate with others and I sometimes wonder how many people I would continue to communicate with if cyberspace did not exist. I think it all comes down to the fact that it is easy and convienient, without cyberspace it would take much more effort to maintain relationships with others so because of the fast pace world we tend to live in, I think cyberspace makes it easier to communicate with each other and keep in touch. I personally am a shyer personality so I think forming friendships on cyberspace would be difficult for me.
