Inside Outside

I've put a lot of thought into why people blog. I think there are several reasons:

#1. People are generally self centered and it is an appropriate way to talk about themselves without feeling self centered.

#2. Some people are looking for fame, like those new "YouTube" stars that keep coming out of nowhere.

#3. There is a specific topic someone wants to share with the world about. Like the people who blog about only donuts or wallpaper.

#4. Blogging is the new way to journal.

Number four is the one I am most intrigued by. It used to be journaling or keeping a diary was a very private matter. No one wanted their big brother to find their journal, read it and then have dirt to make fun of them about. No one wanted their parents to know what they truly thought about inside their heads. So why now is "blogging" the new "journaling?" Are people becoming more and more comfortable with sharing their inner most thoughts with the entire world? Or is it truly because bloggers want to impact other people's lives by sharing their honest inside out story?

I know personally in my blog, which I realize only has four posts, I have been fairly vague about the specifics of what I am writing. Do I need to reach a point of comfortablenss with my blog that I share my insides with the outside? Does every detail, feeling, thought, and opinion really make for a good blog? Or can I keep up with the vague descriptions of what I'm going through and still feel as though I've said what I needed to say?
