A message for Charlotte:
I don't know how else to tell you this so I'm putting it on my blog: I have been commenting on your blog! The problem is, I get a message that says the comment will be posted once the blog owner approves it, and then they never appear. I was feeling a little bit like a rejected 6th grader and hoping my replies hadn't somehow offended. Maybe it's a technology problem and we're both cool people?
As for your very interesting question about why people blog, I am going to weigh in here on my own blog: I write to participate in a community. In my life, I do a great deal of writing in order to figure out my own thoughts, etc. etc.; however, I have many personal notebooks for that purpose. For me, blogging is a way to be a part of this amazing, inspiring community of women who are all on the same journey -- or to have it Co's way, engaging in the same process -- as I/we are. I love reading other people's blogs and comments, and sure, I get a thrill out of receiving my own comments and weighing in on other people's blogs.
My two cents.
