There are a lot of articles out there about the dangers of internet and some of them talk about the fact that online interactions are nothing compared to face to face conversation. Those sort of articles often say that online conversations can't fulfill the emotional needs you have and that people should talk to their friends in the "real world".
Recently, I was reading those article and saying to myself: "if they say so, it might be true". However, I now have a really dear online friend with whom I talk every day online and I'm wondering "is this really true?".
So, is there any serious research comparing a deep online friendship (with instantaneous one on one messaging) vs a "face to face" one? And some explanation as to why an online conversation isn't as fulfilling as a face to face one?
