Blog..

I have no idea what a blog is for..would i really want everyone to read what i write..to know when im sad?or happy?should i reveal myself in a blog? my life wouldnt be much of a mystery anymore will it? The only thing i like about it is that you can update yourself on friends that you havent seen for ages..a good way to keep in touch..can see nice pics also..
well..i will only blog if i have something interesting to share with everyone..and this will be my starting point to express myself better since i dont talk much..only when im in the mood..heheh
