Why having a blog?

I was just checking out the posts on the different Yahoogroups I'm in, and in one someone asked to the group what they use their blogs for. This made me think. I used to have a blog before. I got it at the beginning of the year, and for a while I posted my thoughts. But eventually I found it time consuming and stopped posting. So obviously it was deleted. Now yesterday I decided to create not one but two for my website. What was I thinking? It'll be twice the work, right? Hmm... Somehow I believe that I've got a different perspective about blogging. Now I see it as a tool for my writing career. A way to jog my mind out of boredom. A place where ideas can pop in more freely. And in any case, just a way to make fun of myself and laugh about me.
