Why do i blog

Why do I blog? I've been asked this question enough to make me ponder on it. Many people blog on a specific topic or interest. My blog posts can head in most any direction. If I find something interesting I might blog about it to share with others. Quite often my posts are about a project I have in mind. Getting feedback from others expands my thoughts on the project and quite often determine if I go forward with it or not.
More than anything, blogging is my way of thinking out loud. Do you blog? If so, why? Post a link to your blog in the comments section. I would love to check it out.
