When you think about it, the advent of blogs has been a huge development in the life of our society. I’m no historian of technology, but it seems to me that blogs are the tracts or pamphlets of the 21st century–they provide a wonderful way to unite passion, and ideas with a cheap (free) means of communication.
Blogs have some draw backs too. Because they occupy “virtual space,” there is no (or very little) limit to who or what you interact with on a blog. I can respond to something written by someone I do not know and who is writing in a context quite different from my own. In this sense, blogs create an artificial flatness to interactions and deprive them of the rich texture that can really only come about by knowing something of the writer and her context.
There is also something of a tribalism around bloggers. They run in packs–sometimes more closely resembling a pack of rabid dogs than a herd of placid deer.
Tim Challies provides some insightful reflection on some of the dangers I have outlined above in this post, which is worth a read.
