Blogging is an interesting way to reach others without knowing who they might be. Even when performing before a large audience, actors and musicians can see the people listening to them, but this is just one of the many ways humans communicate to others without ever encountering them in person. For hundreds of years and more humans have written books without knowing who reads them, and for decades people have sent out messages through radio, TV and movies to unknown audiences. But somehow blogging is different from all that. It's quick, like TV and radio, but lingers a while like magazines, newspapers, and other written material. It's both personal and impersonal.
I wonder how long it will be before technological changes or other factors make the blogs we use today obsolete. Maybe hundreds of years from now archeologists will figure out ways to recapture things lost in cyberspace and try to reconstruct our culture. And what might they think of blogging if that ever happens?
