I complained recently about lacking good sources of input. Today, a friend showed me some personal blog-style posts they had written.
I read every one of them all the way through. I tried to articulate what I found so good about them. My thought was that they were written by my friend as if to himself. They weren't really meant to be read. In that sense they were "real".
I could see having a dialog with someone, or a group, where everyone is really just writing to themselves, but letting other people see what they write.
