So, what, people can't do this type of stuff online? The remote team I work with hangs out on internet chat all day long, every work day. We talk about plenty beyond work related stuff. We even post messages over the weekend. We care about each other and our personal lives and have a very cohesive team. Again, this is ebooks vs. paper books. People have a romantic notion about what true interpersonal communication is supposed to be, but when it comes down to it there's no reason why one method of communication is inherently better than any other.
