Why are there blogs?

I've been intrigued by those who seem to want to share their lives with the whole world. Why is this? How Come?

I wondered - until some of our family moved to places far away from Grandpa and Grandma Woody. It has been wonderful to watch our grandkids grow up on the internet. What a great feeling it is to look at them through the eyes of their mom's and dad's comments, photos and videos. We are blessed to have this opportunity. Keep it up!
