I was kinda interested in Seth Godin’s post recently on using a private blog as a diary
“..Use it as an internal diary, a way of tracking each day so that a month or a year from now, you can look back at where you were and how you dealt with the issue of the day. Even if no one else on your team reads your blog, the act of creating it will be worthwhile.”
Outside of a security issue (someone hacking into the blog) it seems like a good idea, as long as the content can really not be accessed by anyone else. I enjoy posting my thoughts about Web Analytics here but it might be that some good content, dreams even, come to us that don’t belong in public blogs but should be in a journal – an online Journal that only the writer can read.
What I like about the idea is you can post ideas and perceptions to the blog from pretty much anywhere you are, as along as you have an internet connection.
